Account not updated accordingly on credit bureaus

I had an account with blue label connect back in 2020 and my account was handed over to DMC due to non payment, on the 16/06/2022 I received a call from DMC notifying me about the account, I then to negotiated for a once off settlement which was sent to me the same day, then I made a payment of R2 831.00 on the 17/040/2022 at 07:27am, I received a paid up letter on the 22/04/2022 from the debt collector and I enquired with blue label connect to check if the account reflects as paid up on their side and they did confirm to me that it is paid in full and they also gave me a paid up letter later September 2022.

I requested them to update my payment history on the bureaus but they never did and when I checked with the bureaus the account was duplicated because of their negligence, they submitted my account twice with different account numbers which I only recognize one, I submitted the paid up letters to the bureaus in order for them to update my payment history, I managed to dispute with the bureaus successfully but with TransUnion it was unsuccessful because the response they got from blue label connect was "the information reflecting on the clients account is accurate", I then sent blue label connect numerous emails to enquire on how can they do such a thing of saying that the account is in arrears while they've given me a paid up letter, they told me that the account is paid up and they've sent my information to the relevant department to update on the CBA portal but they never did.

I even went to the credit ombudsman, NCR and NCC but blue label connect keeps saying that I didn't pay my account in full which is in arrears.

I've been sending them emails on a daily basis, day and night but they just keep telling me that they've requested the bureaus to update my profile but even today my name is tarnished because of this bad company called blue label connect, even today before I write this review I called TransUnion to check if the account is updated accordingly but they told me that since they received information from blue label connect last year June but it came to my surprise that the account is still in arrears while it was paid in full back in 2022.

This company has been making my life a living hell for so long, I trusted them and thought their service is the best but I was just lying to myself, even the cellphone that I'm suffering for was not even in a good condition. I wish they can improve their service because what they did to me it's not a quality service at it's best.
