Dissapointing service - MTN

We have proceeded with an upgrade after we have been informed that the contract is due for an upgrade. We were informed that there is an early upgrade fee payable but that same can be waivered. We attempted several upgrades with the waiver at a MTN shop without sucess, whereafter i contacted the online sales department. I was assured that we can proceed with an upgrade and that the upgrade fee will be waivered and the remaining fee will be divided into the remaining 3 months, whereafter the the upgrade will take affect.

I proceeded and requested the upgrade with an instruction that the upgrade should not proceed if a early upgrade fee is payable.

The upgrade was due on 18 July 2022, and i was informed that the device will be due in 3 to 10 days. After several calls and several follow ups we only received the device on 3 August 2022.

The invoice can and with a shock it became clear that the early upgrade fee was included. The invoice is R700 more than usual.

I contacted the MTN customer swrvices several times to sort this matter an give me feedback. I did not receive a invoice even after several requests to 135 call centre.

I have lodged several queries without any avail...

I only received the invoice on Sunday and it was clear that an early upgrade fee was charged even after it was requested that the upgrade should not proceed if the early upgrade fee will be payable.

I have made several calls an escallstiona and the matter is still not resolved.

I want feedback and the early upgrade fee waivered as requested and promised.

I am extremely dissapointed
