MTN incapable of cancelling a contract

My contract ended on Friday 12th June so I went to my local store to cancel my 2 airtime contracts *** & ***) as I want to go pay-as-you go. <br> <br> I was told I would receive a cancellation notice in 48 hours via SMS.<br> <br> This never happened so I went back to the store On Wednesday 17th June to re-cancel the contract and was told to wait another 48 hours. <br> <br> Still no SMS of notice. I did all of this well within time of my contract invoice date the 20th of the month. I was invoiced for R550 of airtime.<br> <br> On 2nd July my account was debited with R918, not the amount of the invoice. <br> <br> On 2nd July I visited my local store (again) to cancel the contract (again) and collected paperwork to show that I have cancelled this on 12th July. <br> <br> I have also tried phoning the 808 customer service desk (no response after 1/2 an hour of holding)<br> I have logged a complaint with HelloPeter (No response)<br> I have written to MTN via their Facebook page twice. Each time I have had a response asking me to inbox them information, but nothing further)<br> <br> Today (6th July) I tried to phone my local store (no response) and have posted once again on the Facebook page. <br> What a sham!
