Incorrect Billing and Bad Service

Yesterday I noticed that MTN is invoicing me for an account that expired about 6 months ago already. Even though the device is not being used and has not been used in months, my bill for this came to almost R2000 for one month!! When contacting the call centre all they tell me is that I have to log a complaint and that it shows that I have used the data that they are billing me for on their system. I have also requested this contract to be cancelled (even though it expired months ago).<br> <br> No one that I speak to can tell me what happened or how to rectify the situation, all they keep telling me is that if I am liable for the money I will have to pay. <br> <br> The call centre agents that I have spoken to has absolutely no clue what is going on and how to assist me in rectifying the situation. <br> <br> By far the worst service I have ever experienced from a company and I will certainly cancel all contracts with them. If a cent is deducted from my account incorrectly, I will take the process further with the Ombudsman.
