Poor Service which has damaged my Credit Rating

I settled my personal loan with ABSA bank in Feb 2014 and a final tiny payment was taken off in March 2014.<br> 2 months ago I wanted to increase my platinum credit card limit, only to be told by my platinum banker that there is a collection reflecting on my personal loan which was settled in early 2014.<br> Finally with many calls and complaints, I received a settlement letter from the Personal Loans department, which did not reflect the truth in the matter that I had settled early 2014, but that the account has been settled in full.<br> My platinum banker then pushed the letter through to the ABSA Credit Bureau at CCE asking them to please urgently clear the collection and my credit report as this was an error on ABSA banks' side.<br> I requested my credit report from Transunion and as expected, ABSA damaged my credit rating by showing that the account was not paid from March 2014 till it was finally written off as bad debt in October 2014.<br> <br> I am disgusted with this whole scenario to the point where I am wanting to take my business elsewhere...<br> <br> This has now been going on for almost two months. I need to be contacted urgently to have this rectified...
