Struggling to get my refund

On the 04 March 2020 I bought a gas stove and other stuff online and it was suppose to be delivered from Gezina branch then I got a call from them saying they don't have stock and the supplier says they don't supply them anymore. As a result I cancelled the whole order and requested for a refund. Days went by and when I make follow ups on my refund firstly I was told the money will first go into my online profile then later to my bank acc. That didn't happen I called again now am told I need to go physically go to the store to get my refund I explained to them the reason I do online shopping is because I don't have to go to shops and now I spend money and time calling everyday and holding for long only to be told the Manager is dealing with the matter and still talking to head office so like this is unfair I do online shopping so often never came across such a system. So I feel am being taken from pillar to post to get my money. So unacceptable
