Vodacom Remains useless

I had a contract with vodacom for about 8years, last year i decided NOT to upgrade as their customer service has gone to the dogs, nevertheless i decided to keep the number on month to month, I ended up forgetting about my vodacom number and after a few months i realised it was listed on my credit record (my fault for forgetting) I then decided to rather settle vodacom and close the contract completely, however almost 2months later after SETTLING my account vodacom is still listed on my credit record, to make matters worse i cant get hold of anyone to assit me with this.
