Recently I switched two out-of-contract iPhone lines to the Mobile Share Value Plan. The rate was supposed to be $25 per phone (with no annual service agreement), as opposed to $40 per phone if I had a two year agreement still in place. I was told at the At & T store that I would be billed for $40 per month for each of the two phones and then receive a $15 per month "credit" for each of the two out-of contract phones. So, the cost per phone would, in effect, be $25 per month as AT & T advertised on it's web site. Up front this seems to be a pretty contorted way to bill.
When I received my first bill after switching to the Mobile Share Value Plan, the $15 per month credit was missing for each of the two phone lines. I called AT & T Customer Service and they told me that it would take at least two months before the "credits" would show up on my bill. I was assured that they would "catch up" on months when I did not receive the credits and that, in the end (or after several months) The average bill would be $25 per phone as advertised. To me this is totally unsatisfactory. If AT & T is able to change my bill to the Mobile Share Value rate of $40 per month immediately, then why can't they immediately reflect the $15 per month credit for each phone line?
