Can't believe I lost my prior plan for this. Ugh

I joined AT&T a month ago n I can't get good internet service, on top of that I called them and told them that multiple lines on my plan were having a hard time connecting to the internet and they told me that where I lived was not compatible with good internet service. I live in town, close to the interstate and should be able to have a clear, strong connection. On top of that they didn't offer me a lower costing plan for the lack of internet. I have 5 phone and my plan is well over 400 a month, we have a lack of internet, drop calls, and people that could not answer nor fix our problems. Wish there was an undo button, ugh. Missing Verizon already.
