Refund nightmare

Do not buy from any studio 88. They are quick to take your money but when you have to return something it's a complete nightmare. They only refund in cash which is good but they never have any. No reserves. Nothing. I phoned 8 stores in Johannesburg and they all told me they have no cash because it's a slow week for them. How is that my fault exactly? They have also said that they don't do refunds to cards. So how am I supposed to get my money now
