Bad Service!

I love the TFG brand. Having an account, I wanted to buy some stuff. I was told because I haven't used the account, I need to apply for a new one, which was declined. They told me I was declined because of an old outstanding payment. If they app**** any customer service and were proactive, they would've seen on my credit report I have no outstanding accounts. I did some research and discovered the account they referred to was already paid off in 2018 - I even sent them proof! Clearly, TFG is not interested in retaining customers!
