Can I cancel online trade-in then complete trade-in in AT&T store?
I just received materials for a trade in I initiated online 9/25. Now I have a second phone to trade in, so I would rather bring them both in to the store. I was told that once you start the process online it has to be completed by mailing in. So I am wondering if I can cancel the original transaction it and bring both in. I hope that I explained that clearly. Thanks in advance!
