Dishonest

I called AT&T to change our plan to the new family plan 145.00 unlimited text/phone and 10GB shared.  When I called I told the customer service rep I was going to purchase a new line for my daughter at Target for 119.00 and since I was due for an upgrade possibly upgrade my phone at Target as well she didnt say anything that we had to purchase on the NEXT.  My husband went to target and purchased the phone in the begining of May Target also did not mention our existing price for our plan would change.  A month later I decided to upgrade my phone and since Target still had the 119.00 sale I went in to Target and upgraded my phone.  I went in told them I was due for an upgrade told them I wanted Iphone 5S and they pulled up my account to confirm I was due for and upgrade and that was it.  We even paid an activation fee for each phone 36.00 at target.  Yes, now im paying 40.00 for each line vs 25.00.  We were grandfathered into the old family plan 700 shared mins unlimited text and unlimited data.  The only reason we changed was because my daughter is going into middle school and would need a phone.  It was a plan that would work for us but now we are not going to beable to afford 195.00 every month for 2 years.  All  Im asking is for my plan back.  I have already looked into going to Tmobile even though I know I will have to pay 1/2 for 3 new phones Im willing to give them my business then work with a company that wont help me since we have been with AT&T for years.
