Jet vaal mall worse service ever

I would like to complain about the service I received at Jet in vaal mall.I did a laybye and went to cancel it on the 25th before it expires but I did not have the slip, however I had my ID and the sms messages for the laybye. The laybye was canceled and I was charged a a 1% fee which was fine, what was not fine was that they refused to give me my money back in cash and said I must but something and if the money is not enough I must add, that is unacceptable as it's my money and I can choose what to do with it, I wanted to still buy something but use my card eft, they said no, I asked for the supervisor Seipati Masilo and she was rude and didn't want to listen to me as a customer or value my support to jet, Jet should train the so called super visor on how to handle difficult queries and there is always an option, I wanted to leave the cash refund and swipe for the items I bought and they refused again which they waisted my time and I wouldnot recommend jet in vaal mall the service is pathetic, I normally buy at jet Sandton of Jozi which I never experienced any pronlems
