Shocking Manager at Big Blue Mall of Africa

Big Blue- Mall of Africa I went to return a shirt today for a refund, the store manager James then stated that they do not give refunds on previous returned items only a voucher? Firstly there is no mention of that on the back of the slip and secondly it is in conflict to the Consumer Protection Act. I then had to phone head office, who approved the refund. Of course the Store manager seemed to be displeased with the outcome and started being rude to me, when I asked him to stop being rude he started screaming at me and accusing me of being rude. Totally disgusted!!! Will definitely never step foot in that store again!!! All that to return a T-shirt.
