Billed 3 years after contracted ended

To whom it may concern

In 2012 a 2-year contract was taken with MTN for an internet service. After the 2 years, NOBODY contacted me to enquire if I wanted to continue with the contract, hence automatically it was supposed to be converted to a prepaid sim. I have not received ANY communication from MTN up until 2017. This is 3 years that I was not informed about any debt owed or contract that is still running. NO funds were taken from my account either. In 2017 money was just deducted from my account without ANY communication once again. I contact MTN and they told me to revert to the ***** department, how is this *****? I responded and one again NO response. After I stopped this amount from going off and contacted MTN numerous times, there is now 2 amounts being deducted from my account. Does the MTN accounts department even know what is going on? What are these amounts for anyway? I will not be liable for ANY of these funds as I never used the sim card after the 2 years were over and I NEVER received ANY communication from ANYONE up until I was handed over to the lawyers. If this situation can be explained to me, it will be greatly appreciated as I will NEVER make use of ANY MTN service in future. This is unacceptable, unprofessional and absolutely *********. Should you need to speak to my lawyer, I will gladly provide contact details.
