No response from superbalist for faulty watch

I bought a watch from superbalist and it arrived in August last year. The watch fell apart in december. I contacted superbalist for a new watch and they said it can only be repaired cause they have no stock. When I refused the repair as it was within the 6months and according to the CPA I do not have to accept the repair, they came back and told me all costs for repairs will be at my cost. I then filed a complaint with the CPA ombudsman and they said they would get back to me but I have heard nothing in weeks. I would like a new watch as I paid a fortune for this watch and I expect a response which I never got.
