ITC Listed Due to *********** staff and NO one willing to assist!

Over a year ago in June 2015 we moved from Cape Town through to Durban. Before moving I visited one of your stores to find out what the process is for moving provinces and accounts etc. He informed me, that I could simply transfer the line when we arrive in Durban. To my surprise after visiting a Telkom branch this wasn't the process and Telkom cannot simply "transfer" a line, I would need to cancel the line and take out a new one in Durban. So, I cancelled the line, paid my account up to date and decided to rather open up a Telkom Mobile account as I found out our new place in Durban doesn't have a land line and I couldn't wait 2 weeks for an installation. Last week I went into FNB to apply for a loan and to my dismay, I was rejected because I had unpaid debts on my credit record and low and behold, Telkom! Upon further investigation I came to find out that the line wasnt in fact closed OVER A YEAR AGO and that I was liable for a further R230 and now my credit record is listed because someone didnt do their job properly. THE WORST part is when trying to sort it out and trying to get a simple letter to send through to ITC to get my name cleared, no one can point me in the right direction, help me fast track my request or assist in any shape or form. TELKOM IVE PAID MY ACCOUNT, IM UP TO DATE NOW HOW CAN I CLEAR MY NAME BECAUSE YOU PEOPLE CANT DO YOUR JOBS PROPERLY!!!!
