Unhappy customer

I have called MTN in November 2019 and 4 times during 2020 to cancel my contract as I have lost my job wihich I clearly explained to every person I spoke to. I have been calling them to ensure that this will be done but MTN (Joshua) decided to renew my contract instead without my consent. I called in again this morning as no one has called me back as promised by MTN, and as usual I have been transferred to so many different departments and still no one can help me!! Today I am told that they cant help me as Joshua is from KZN, are they not one company and can nobody take ownership and resolve the problem? Seems not, they always pass the buck and never get back to the customer as promised by numerous staff members. I need my contract cancelled with immediate effect, with being unemployed I cannot afford to have this contract but informing them to cancel means nothing and they do as the want. I will be cancelling my debit order and then letters of demand will be received isnt that how they operate? In my experience over the last over 20 years with MTN has never been pleasant. The only reason I stayed with them is due to the fact that i was under debt review and could not get a new contract at the time. I am still waiting for a manager or anyone in fact from MTN to honor their word and call me.... What can I say the service as per usual is a total disgrace... I am saddened to say that I will never ever go back to MTN!!!
