Poor customer service

In 2020 I opened an account with the Fix around march it was locked down and I was unemployed and did not use the account nor take anything with that account around June I was called by the debt collectors saying that I'm owing them and my account was handed over, I contacted TFG regarding the matter and explained that I'm being contacted by debt collectors I was then told that by TFG that I took a funeral cover with them I told them I have the contract and never took any funeral cover with them I was told this will be resolved it's been now 2 years and iam still not assisted I'm always assisted by different consultants but there is no solution ,I called again TFG I was told that they paid up that account and it's on zero and I should ask for a paid up letter to DMC I called DMC and I was told that the account was not paid up it's still shows a balance I again contacted TFG the consultant told me they will investigate on their side why but was not given the reference number it was July 08 then yesterday I called to follow up and the consultant that was assisting me told me that there is nothing written about an investigation on their side and he had to write again and will send the matter to recovery department I'm really ****ed of by TFG on how they are handling my case its 2years now still am not assisted and this is destroying my credit score I cannot get anything anywhere because of this....iam not happy at all.
