We have been overcharged by the thousands in the last year by ATT Cingular 2007 2008. For mistakes that they said they would fix yet never did. They did not adjust or credit our auto pay with free phone credit and did not reinburse our visa accounts. Yet instead they continued charging us the regular rates + the overcharges. In gross amounts exceeding our monthly charges that are normally supposed to be within the under 500 a month limit. Instead they charged us in the 1000's.Now we are being bounced back to different offices within the ATT corp. Because nobody seems to want to reinburse us back to our now, over the limit visa.

The unfortunate thing is we need this plan. No other cell carriers honor the North American plan which covers US, Mexico, Caribean, Canada and Alaska. We have to pay because they will ruin our credit.We have notated the account as not paying until they sort it out and it cannot effect our credit until we reach an agreement
