Attitude problem

Hi I went to credit some tiles that I did not use at the tile africa in roodepoort. Was assist by Hasim who made a mistake by crediting me with more than wat I was crediting.for the issue to be sorted out he called his admin manager that did not want to speak to me ,who spoke to Hasim in Afrikaans not speaking so that I could understand in English but luckily I know the language I could hear and understand what they were saying.she just said it will be fixed but never fixed it just went back to her office leaving the guy to call banks about my card as I refused for them to stop it again as I had to wait 10 to get my money but it should be easy for them to get theirs as they don't trust me.after a good 2hours of being in the store no solution and no manager wanted to assist.then decided to call the store manager who also did not want to speak to me just to the staff member after I asked him who called him then told me again he wants to stop my card again of which I refused again.another hour with no solution.then eventually I was given my card to be told to bring back the cash I owe them when it's refunded in my card and all bank charges they will refund me plus my petrol for traveling will be refunded. As soon as the money reflected in my account I went there to give them the money but the store manager and admin where not in .did the refund to be told all was promised will be done as soon as the manager was in.its now 5days they have never called me.all was promised did not deliver.i kept my promise to bring back their cash.wat did not make me happy is that we treated like nothing do to our skin colour in such places.
