Incompetence

I called your call center to cancel my *** and they told me that my account is in arrears because the new number that was allocated to my account in October falsely by one of your agents has put my account in arrears and I was told that it will be credited and my account will be updated but that's not the case. I'm honestly tired if fighting, can this be resolved. I spoke to Dimpho Dimpho and she couldn't help didn't even try to take a good look at my account or get assistance from her superior. This is pure incompetence
