Poor service

My account with the fochini group was closed in April 2015. A paid up letter was received from consumer friend advising me of this. I recently found out that a DR interest was still reflecting on the supposedly closed account for the amount of R389 and fochini DID NOT update there records and remove this amount and let it to reflect on my credit status. I queried this on Monday and I am still awaiting feedback as to when will they contact the credit bureau and update them. I have been calling consumer friend everyday and I keep getting told that TFG hasn't provided any feedback. I am totally disgusted with the lack of immaturity TFG is handling my query.
