TFG bad service

Very bad service and client relations from TFG. Made an oline payment on TFG website with their snapscan payment option. Getting threataning messages and phonecalls from them that my account is in arrears for this month. I spoke to a lady called Glenda that gave me an email adress to send proof of payment.

Todai i receive a message that my account is suspended until i pay this and next months installment.

How does this work for customer service. I made an online payment that reflects on my bankstatement that it was paid, then due to TFG incompetance online services they suspend my account after not according to them missing one payment.

Is this the way TFG treat long time clients. Had to go in to a store and make that payment to reactivate my account.
