Cancel your contract with cell c

I went to cell c pavilion and I have never experienced such bad service. I went to do a sim swap because I ****** in december and i went and blocked my number and phone,at the time I didnt have ID book because that was in my bag that was ******. I went and got a temp id and had to open a case and had to get affidavites. I have been to all the shops were I card store cards to replace them and all of them were helpful besides Cell c. I went in and the lady who was on the desk tells me they dont accept temp id with affidavit and i ask why ans she tells me she doesnt know why but they dont accept and she does thru to the manager to confirm and comes back and says no. I ask to see the manager and she tells me no the manager ans sick and not seing any customers. If the manager is sick why is he at work??? Eventually he comes and he didnt even try to hear mystory he just said no and when i asked his name he thru his hand and asked the staff to give his details and he left. Cell c please tell me what kind of employees do you employ,is this the kind of service one is to receive especially from a manager??? All they could say was his name is Avi
