Terrible service - cannot get anything changed.

I am currently due for an upgrade and i have been struggling to upgrade and get the iPhone 11.

Vodacom is saying that my credit score is too low. I have received my credit report from the credit bureau-Transunion, which shows not only that my credit is up to date but that my credit rating is one of the best.

Have been to the store, consulted telephonically and everybody at Vodacom has their own version of what could be a problem, sending me from: Upgrade department, Accounts department, Customer Acquisition etc. I have been pushed from department to department with no assistance or resolution. There is no reason why my credit score is so low at Vodacom and fine everywhere else, including the credit bureau's.

I would like someone at Vodacom to assist me increasing my credit score (that is clearly incorrect on Vodacom's system) so that I can get my upgrade. I don't want to go through tons of departments again to get this resolved.
