MTN & ADMYNTEC – Ongoing Unauthorized Billing, Credit Listing & Failure to Resolve

I am posting this after nearly a year of trying to resolve an issue that should never have existed in the first place.

Account Number: BA116666084 Latest Invoice: MTNRO538220 (25 February 2026)

I previously had a contract with MTN which I formally cancelled earlier this year after paying the required settlement amount. The account was closed.

Thereafter, without my knowledge or consent, an additional product/service was loaded onto my account. I did not request it. I did not authorise it. I did not sign for it.

For the past eleven months, I have been billed monthly for this unauthorised product.

During this time:

I repeatedly emailed MTN asking who authorised the addition.

I requested proof of consent.

I asked to speak to management.

I received no clear answers.

The billing continued.

The account was allowed to go into arrears.

I was listed negatively on ITC, affecting my ability to obtain finance.

It later became apparent that ADMYNTEC Services was behind loading this product. After several heated exchanges, I received an SMS confirming that the service had been cancelled.

Despite that confirmation, on 25 February 2026 I received yet another invoice (MTNRO538220).

At this stage, this is no longer an oversight. It reflects a serious breakdown in internal controls between MTN and its third-party service providers.

An Ombudsman complaint has already been lodged and is under investigation, yet billing continues as though nothing is wrong.

The facts are simple:

The original contract was cancelled.

No consent was given for any new product.

No proof of authorisation has ever been provided.

Credit bureau listing was done on a disputed, unauthorised charge.

Cancellation confirmation was received — yet invoices continue.

This situation has caused unnecessary financial prejudice and ongoing administrative frustration.

I am still awaiting:

Written confirmation that the balance has been corrected to zero.

Removal of all adverse credit bureau listings.

A full audit trail showing who authorised this product and on what basis.

Assurance that no further invoices will be generated.

Consumers should not have to fight for nearly a year to correct a service they never agreed to.

I am documenting this publicly because private channels have failed.
