Poor service from the complaints department

I am a loyal customer to TFG, but the service I have received from the complaints department which I believe this should be where your customers escalate to get quick answers and resolved issues but at this point I feel like that department is totally useless. I have been making payments without taking any credits at least for the past 3 months, apparently these payments are not reflecting on your side and had it not been for the reports I get from ClearScore I probably wouldn't notice this, so I took time out of my busy life to write a long email with the questions I have about this account as well as proof that I did make payments. But the only thing I received from these long trail of emails was a statement and an acknowledgement that I did pay but the payments are not showing on their side and so I need to go to the store with proof of payment because they cannot trace my payments from a bank statement. How is this possible? The bank statement clearly shows the store, the amount and date of transactions on top of that the store always keeps a store copy receipt with them as proof (this is besides the proof that should be in the system). What ****es me off mostly is that there are multiple people replying to my emails but they all ignored my requests.

I have included the subject line of these useless emails in the reference number field 😒
