MTN ARE *******

I'm so tried of mtn, I was charged R1595 last month on my R399 account, I visited the Galleria branch on Sunday 26th September and got no assistance, the staff are unhelpful and service is poor, when I asked why was I charged so much, she asked which branch I took my contract and said she can't help me as the contract ended on 6 September and they are charging normal rates, I never got a call saying the contract ended or it will end, when I asked must I cancel an expired contract, she said yes, when I asked to speak to a manager, she stated there was no manger, when I asked to speak to a manager, she said there was no manger,I asked for an email she said there is no email.. unlike telkom whom actually call you to update you, mtn are a bunch of *******. I was told you cannot cancel your expired contract on a Sunday as that department is closed. I called several times on Monday, got nowhere, waited on the line for more than 30 minutes at a time, spent R300 on airtime as I use vodacom. Finally found an email on Google and emailed numerous times, still no luck, in cancelling an expired contract, at one time I spoke to an operator took my number down and told me she will call back, no call. With no success I pulled out my router hoping that it I'll help I was charged again today R1595 without using any data for 1 month. Going forward I don't know what else to do. What do you do when they say, you can't cancel an expired contract, only by calling, but no one answers your call. I have now stopped the debt order and lodged a complaint with the ombudsman. Please someone assist me what can I do. Its heartbreaking to work so hard and have a company to Rob you 2 months in a row for R1595. Mtn are *******, I suggest never to have a contract with these people.
