I'm trying to upgrade a line by buying an iPhone via BestBuy. In the process, I have to type my phone and last 4 of my social so I can authenticate with T-mobile. It then gives me an error that my phone nad last 4 of my social don't match.
I've been to two stores, both stores told me to call T-mobile or use Twitter. Twitter support told me to go back to a store and when I called T-mobile, they also sent me back to a store. I need to check if my SSN was correctly typed in the system as I've only had this plan for 5 days.
How do I fix this?
