terrible service,poor staff skills

please do not take contracts with cell c ,they over charge on your debit order,they actually did ***** on my bank account by double debit me.if i did not look at my bank statement i would not have known.also they still did not sort out they mistake . they agents working there are straight out of school kids with no experience even the manager tsepo rude a hell,they make everything the customer fault,i tried explaining to him that cell c made a mistake which i have been trying the whole of 2023 calling the customer service department begging them to correct my contract,that to when u call its so rowdy like a circus people screaming in the back ground and that is not professional,i eventually spoke to a lady from social media platform at first she was im so sorry sir we going to assist you,it will take us 2working days and by the third day they like you need to pay R4000 or we will hand you over.i mean why would i have to pay R4000 for a contract which i have not used since past year because of the useless people at customer service whom do not know how to cancel an extra contract which was a mistake made by them and to change the debit order amount to the correct amount .why is it so difficult for cell c to do that?are they really professional?could it be that because of poor staff working there making mistakes all the time?in all fairness the agent whom made the mistake on my contract should bare the brunt of the issues im having ..come on cell c catch a wake up before its too late and teach your staff some manners..
