MTN - Disappointed

MTN service is pathetic. For two weeks we are trying to upgrade my husband Andre van der Westhuizen ***. Now we want to cancel both his contracts with MTN. We tried doing this on the 19the of January 2022 at 14h25. We spoke to Neeren Govender at retensions. She said she will get back to us. Still nothing. This is not the first time we tried to cancel both contracts. Guess I will have to go to all social media and give them all the info who we spoke to several times. How long we have to hold on to get through etc.
