Refund not given

I had a watch on lay bye and it expired in January. On 01 February I received a sms saying if balance was not paid , the lay bye would be cancelled. I did not pay this and understood that it was cancelled. I went Chatsworth store on 10 March to receive my R600 refund and was told that they don't have cash and I must come back at another date , I explained that I l now lived in Phoenix and it was quite a distance and expensive for me to keep travelling back and forth. They then told me that the lay bye was not cancelled and had been renewed to May , at no point did I request this . They then then said that they would cancel the lay bye and I could pick up the cash at the Phoenix branch. I called the Phoenix branch yesterday and was told that they also did not have cash to refund me .This is frustrating because it means if the store doesn't have enough cash for the next month I must now wait for a refund .I requested for the refund to processed on my card when I was in Chatsworth and was told that it couldn't be done. Please can my refund be done as I can not afford to wait until American Swiss can afford to pay my refund.
