Billing and upgrade

2 issues:

1. Last month I received my invoice. Noticed that my bill was more than what I normally pay. Called MTN from around 5 July to request they sort out the billing error. Was given ref number and told I should call back the ff day. When I called I was assured the issue is sorted nd my debit order will go off as per usual. Ff week my account was debited with incorrect amount. Been calling MTN since and was told the query was resolved but there's no notes or reasons why my acc was debited with extra amount. Was given another ref number. Called again and was told it needs to be escalleted again because that department doesn't have access to my invoices. Imagine.. Now a month later my billing quiry is still not sorted. Call centre agents are not helpful.

Ref:*** 2. My data contract is due for an upgrade.

I went to MTN store at Springs mall for an upgrade. I was told my application was declined due to Credit checks. The consultant processed it twice and still declined and said I must contact Transunion to check why it declined, because there is no specific reason given by the system.

To the best of my knowledge, I don't have any adverse/ defaults on my credit profile. I receive my credit report every month from Clear score, and my credit score is high. About 666.

Anyways, I called Transunion and was told there is no there are no reasons showing on my credit profile as to why the application was declines, everything looks okay/normal. No defaults, late payments etc.

A day later or so I called MTN customer care, and spoke to Upgrde consultant, to try and upgrade the contract via telephone.

Application was still declined due to credit check, and no other specify reason as to why exactly. The consultant asked if I have ever skipped my MTN account payment, said never.

Was told I need to try and apply after 3 months.. I don't understand why my application was declined where as I have no issues with my credit history / profile. My credit score increased over the past month even. I need an explanation/ reasons why my application was declined.
