MTN Customer Service is non existent

On 14/08/2020 I upgraded my contract. My new monthly installment should be R350.

The below is what has currently happened.

- End of August installment was R870, which I understand and agree with. - End of September installment was R870. This is incorrect. - End of October installment will probably be R870 again (as per the statement I've received). This again, is incorrect.

In the beginning of October I went to the Tygervalley MTN store, whereby they advised due to them migrating to a new system the upgrade wasn't "put through on the system". How is that my problem?

I phoned the MTN customer service and they advised on they system they can see the upgrade happened in October. Which means, the Tygervalley MTN store only put through my upgrade after I visited the store in October.

This is totally unacceptable that I'm being charged for my old contract amount even though I have physical proof that my upgrade happened on 14/08/2020.

Please note I will be logging a complaint on the ICASA website by close of business today if no response has been provided.

I'm expecting my account to be debited with R870 again this month. MTN will then have overcharged me by R1040 for the past two months.
