COMPLAINT CONTRACT UPGRADES

Very disappointed with MTN and The Grove outlet, was invited for upgrading my contract which I have been having with Mtn for over a decade, now going to close to 15 years but am being treated unfairly because there's a negative listing on my name with Safps even though I do provide Mtn with evidence of this listing they still don't want to assist me getting a data contract and upgrading my current contract number. This is annoying really, I have been loyal to Mtn even when I wanted to cancel contract was persuaded to stay on which I did, spoke with retentions department on Wednesday they informed all is well and can go upgrade but when I get to the store am told it's not possible, this is annoying and frustrating honestly, can this be escalated with the Mtn legal department to deal with my matter and find a solution to resolve this impulse as soon as possible or better advise me on how to cancel this contract or account which is useless, for all sake l am not a ******** and this listing by Mfc and Safps is useless, but will expect from Mtn to treat me with dignity which l deserve as one of their loyal customers for so many years
