Bad Service I received from MTN

MTN has failed me very bad. I need someone to assist me with more information to report them to Public Protector. I have logged number of calls and wrote emails to retentions and with no respond. My router was upgraded June 2020 up until now I haven't receive the router and in September 2021 my contract was changed without them notify me. NOW, I have been asked the contract agreement of something that I am not I ware about. I called sales to explain to me and they drop calls while I am still talking. When you call customer service and they transfer calls to retentions . You can hold for more than an hour and the call drops it's self.

I hope consumer Act are reading our complains. My phone and router has been blocked by them and no one call me.
