Not sure where to post this

[orderssn]

One payment method has shut me out - interrogated me and then said that the person  I was paying was receiving too frequently. NOT my fault. There is only one other option and I want to avoid the same thing happening. I'm sure you all know what I'm talking about. And yes, in person. Any advice? A favorite seller I don't want to lose but options are limited.
p.s. If I posted anything inapprorpriate, please pull !
