First time post and user. I just signed up with the One app last week. I just bought 3 $200 MCGC from OM (BHK 511332 11/23 exp). I registered one and set the pin and waited a day. Yesterday, I went to the Money Center and asked to load the whole $200 via the barcode on the app. I said I had a debit card. I swiped, put in the pin and got an error. Unfortunately, I don't remember the exact code that came up. I walked away since not pushing it was a recurring theme in the posts. Are there any glaring mistakes in what I did ( wrong GC, setting a pin, going to a MC, etc.)? I'd appreciate any pointers. Thanks.
