Scam

$125 for what? 

If you are looking at a colorful document called a customer service summary, that is not a bill, it is not a even a good estimate of what your bill will be. 

While you are gathering that information:

    Your first bill will be high.  It includes more than one month's service charges, activation fees for each line, and all installments even if you have participated in a promotion which will eventually provide Bill credits making those phones free.  If you are eligible for a discount on service, including the auto pay and paperless billing discount which is stackable, until those are verified those are not included in your bill. 

AT&T's prices are published online. You can also find their discount program if you Google AT&T signature discount. If you are an Internet customer, you get 25% off of your wireless if you switch to AT&T. If you participated in phone promotions, Bill credits take 3 months.

Anything I didn't cover? 

Your answer is clear that you are from the company, the offer by phone and its a recorded phone call, why they don’t go back for it, you will convince me a company like at&t does not have record or track to whom who made the offer , all what they know is how to make bills

Good lord 🤦‍♂️

Nothing she said means the offer was false, just giving you additional information. You ignored the part of the post that directly dealt with your issue.
