Pathetic service once again from cell c

I would actually like to give them minus five stars but no options for that . I am still struggling to finalise a contract upgrade initiated in early January 2021. After many phone calls and no response from them I complained on this platform and within one day they responded . Eventually , the matter was resolved ( this took a few weeks ) despite the complaint . Or rather I thought the matter was resolved . To my surprise cell c then decided to bill me a lot more than the agreed upon price for a contract ( which was allegedly resolved by them calling me to say that the agreed upon price is what I would pay ) . My statement however says otherwise and My account has been debited with almost R800 a month more than it should be . I have called a few times but each time am told they are busy with the query and will call me back . The last time I called them was the end of March and was told they would Call me within 24 hrs . I’m still waiting . I received a courtesy call from a cell c agent asking me if they could improve their service , I informed him he could ask the agents dealing with the case to call me but was informed that he can’t fulfil that request . I am now stuck in the middle of a contract that was renewed , debited incorrectly and no one to speak to . I have dealt with many companies with poor service but cell c is infact the worst I have come across . I was also told on the last call I made when I asked them to call Me back if the call cuts (as it takes very long to get to speak to an agent as the call centre is not the best in terms of connecting one to an agent) and was told it is not their policy to call back if a call cuts and the client must call in again . I have had multiple calls dropped with the many calls I’ve made to them due to them being unable to transfer a call or just that their systems cut the calls . No one has ever called back . If I was not stuck in this situation I would Move to another company .
