Not ever take up any contracts with MTN

What a waste of my time resource and money, its been about a month trying to cancellation my month to month contract that i took with MTN this is very disappointing called 135 to find out the cancelation process consultants mentioned to take the router to the store i did that they gave a form to fill in did so to book the device to the wear house. I received an sms stating that the device has been booked i called, i was also advised to call 135 which i did now they telling me to go back to the store and cancel this contract where initially took the contract, i did mention to the consultant over the phone that i took this contract telephonically and that i did not go to any storr to get this contract, but now i must go back to the store that said i must call in yo cancel... Why is it that i must do so much i dont use an MTN simcard in my day to day phone so i have to buy airtime to keep calling and using money to run up and down to the stores! This is very disappointing service from MTN abd i advise people to never ever take any contracts with MTN because they misleading and deceiving and this is not a fair way to treat your customers
