No. I think the replies are based on your need to lie to get out of an $18 fee. It's cheap, stupid, and sad.
AT&T doesn't care. They put the $18 fee up just so they have something to give customers who have complaints, any complaints.
The rep you are talking to doesn't care, they just need you to complain about literally anything so they can give you the $18 credit and get you off the line + get a good survey if you were randomly selected.
You don't care, you know damn well you'll get the $18 credit no matter what - why not say "someone else already got to this point with me, but seems to have failed to actually remove the charge" and save all parties involved time and money.
I find it downright hysterical that anyone would care about this particular lie, literally nobody involved in the process has any bit of care in their cup.
Sure, the O.P. could have just as easily raised a stink about something else and they would have offered to remove it anyway (since that's it's purpose) - but how is that any different in the end?
As someone who worked in a call center for a while - everyone, everyone knows damn well that the O.P. was lying. They simply don't forget to put things like that in the computer, or at least note the account that they had intended to (they type the notes up while talking to you). Nobody gives one flying **** though, since it frees up the line for other customers sooner, gives the individual rep a significantly higher chance of getting a positive survey, and the company created the charge just to make customers happy when they remove it.
Nobody was hurt, everyone was - in fact - better off for it.
The annoying customers are the fishers, who won't just come out and say what they really want (a credit of some sort) - but will complain about unrelated things until you guess. They just take up the call centers time when a quick dirty lie could do the same thing so much faster.
If they gave even half a **** they would get supervisors involved and make it turn into a 30 minute process to give the credit - which would cause most customers to give up/hang up before getting the credit. Instead, it takes 2 seconds and no supervisor - because it's a ******** charge.
