MTN Empty promises of refund after strike

I spoke to Slindile Mdubo and Kubera who ensured me there will be a refund coming for charges that was put on my MTN account when I did not have a phone - this resulted out of the strike. Kubera logged a query and insisted when I called her in September that she will follow it up and make sure the refunds are processed. Slindile Mdubo send me a confirmation email that this is what MTN's commitment to their customers who were affected by the strike. However we are now in October and I have yet to see a refund for the May and June debit when I actually were not even send a phone. All I seem to get from Kubera is false promises and Slindile does not even have the decency to respond to my email queries. I am very very frustrated and discouraged - yet again - by extremely poor service delivery and false promised from MTN.
