Why offer a service you can't provide?

There's about 90 four letter words screaming inside my head right now from my anger, but I'll refrain from using them in respects for the other users who may not appreciate such language.  Just keep in mind that's exactly how livid I am at wasting my money month after month after month on a service that is so lackluster and slow it's like watching an elephant running through a tar lake whilst dragging a dead elephant behind.  That having been said, let's get on with the complaint.

Firstly, I live in a coverage area.  However, the nearest AT&T store is 98 miles away.  Let me repeat that in case you missed it...98 miles to the nearest AT&T store.  So ALL of my complaints and technical issues must be routed through 800 numbers with customer service reps who clearly don't care about customers like myself.  I've called support dozens and dozens of times in the past only to finally give up on trying to get anyone to work with me.  However there are only 2 options for cell service here, Verizon or AT&T.  Believe it or not, with all the problems I'm about to post, AT&T is the lesser of 2 evils.

I pay roughly $107/month for 2 cellular phones.  One is an iPhone 5 and the other is some cheap LG flip phone.  So automatically I have to pay the smart phone premium and am required to pay for a data package.  That having been said, my data usage is slim to none at my home.  In fact, I don't think I've ever seen a 4G symbol here at home, let alone a service icon.  In order to use my data I have to drive into the heart of the city and park my tail feathers essentially under the cell tower to achieve any sort of data signal.  Even still when I do that the service is slower than the aforementioned elephants.  Surprisingly, sometimes the LTE symbol will light up instead of the 4G but that makes no difference in speed.  This is neither here nor there though, because why would I drive miles out of my way to use such crappy data service?

If the data service wasn't bad enough, and I could go on for about 8 more paragraphs on the subject, my call/text service is on par with it.  My service at home, once again, is 0. Occasionally I can get 1 bar to show up but forget trying to use that bar, it's only for show.  So after much complaint to AT&T about this they sent me an MicroCell device to connect to my internet.  Great, right?  I only have to pay another $75/month for internet in order to get my service working at home.  It's a perfect solution...not.  

Now that I have the MicroCell device, I am able to make calls and texts from home.  That is when the device is working or I'm within 10 feet of the dumb thing.  It constantly loses signal and if it's not losing signal the strength of device's wireless signal is so weak I can't leave the room it's in without losing service or being reduced to spotty service.  For instance, I can't lay in bed and text or call, can't go to the bathroom without questioning the signal strength, can't be in my yard and take a call, the list goes on.  It also has hiccups on a near daily basis where it will not work for a couple hours, usually in the middle of the night, such as right now.  I can do hard reboots on the MicroCell device and on my cable modem (which is flawless) and nothing will remedy the downed service.  This only increases my frustration and rage.

In the past I would just call AT&T technical support and complain, only to have them tell me there's nothing they can do after hours on the phone monotonously going through the same motions each time to troubleshoot everything on my end.  I usually get too frustrated at this and end up just sulking at home until the issues remedy themselves.  The technical support is about as useless as the service in my opinion.

I could go on and on and on, but I'll start to conclude this rant and move on with my questions.

Why is it that I have to pay the same insane price as everyone else for a service that I never have?  Why is it that I have to pay for an internet service on top of the already insane cellular service price?  Why is it that I have to tolerate poor quality work arounds for the less than poor quality service?  And finally, why does AT&T offer a service to me that they clearly cannot provide?
