Regretting becoming a TFG customer !!!!

I have been harassed everyday for the past week for an "overdue payment " on my account, while I made payment on my account on the 25 April 2025 already. I emailed the customer services department, forwarded them what they requested and 2 days later still no response from them. This morning again i receive an email for payment and my account is at risk - for what ? when payment was already made - i sent another email still no response.

when all that needs to happen to to allocate my payment to my account i dont understand what is so difficult about it - and all this is going to negatively impact my credit score - which is not my fault !!!
