I'm very grateful the bank caught it and put a hold on it until they heard from me. Not only do I not know anyone named Thao in Colorado, I currently only have $820.95 in my account.
As Chase's fraud department and I went through recent account activity, it seems someone tried to set up an Apple Pay account and abandoned the effort. No, it was not me.
I had to change my username and password, as well as the password on the email account connected to my bank account.
Upon reading my travails of yesterday (post below), Country Dew wondered if I wouldn't rather pay "with a chicken and a loaf of bread." That does seem attractive, doesn't it? I also now long for landline phones with rotary dials and checks with a cashier checking the signature. For while all this progress makes my life easier, it also leaves me more vulnerable.
