HORRIBLE SERVICE

I have been trying to contact the MTN Cancellations department from the 17 September 2021 with regards to my Contract. Rewards SA messed up my contract and signed me up for a further 24 months which I need to cancel. I cannot get hold of anyone from Rewards SA, and i have been holding daily for about 90 minutes to speak to a person from MTN to correct this. I even went to the MTN shop at Mall of Africa and they were unable to assist me. While at the store, we held for 40 minutes only to be cut off my the MTN consultant.
