AT&T employees may not always have your best interests in mind when you trade in your phone. One customer reported being hit with a hefty bill of over $400 after trading in their phone, due to being mistakenly signed up for two lines instead of one. Despite being advised to change numbers to expedite the process, the customer ended up with unexpected charges for both the new and old lines.
Input from other AT&T customers revealed that deactivating the extra line and resolving the issue could be a challenging task. If left unaddressed, the additional line could become a persistent problem for the customer. It is essential to thoroughly review all agreements and terms before finalizing any transactions at AT&T to avoid unexpected charges and complications.
