My daughter and I have dispute of monthly charges and initiation of service dates with AT&T. Our conversations with AT&T representatives regarding erroneous charges on my bills have not been resolve yet. We thought we did! According my records we agreed to pay $481.39 to settle the account. In the mail, we received periodically bills from AT&T charging different increments: $723.08, $741, $801 etc. This account should not be in collections. I am not sure what I supposed to pay or where I suppose to send the monies. I received a collections letter yesterday, Feb 25, 2013, charging me $1,446.55 ( AT&T $1,225.89 and AT&T Fee $220.66). I am disabled and on fixed income. Now my daughter credit is ruin! I do not know what to do. Please advise. Thank you for your assistance.
