BAD SERVICE RECEIVED FROM MAKRO POLOKWANE

On the 1st February 208 I have purchased a fridge from Makro Polokwane. We are experiencing problem with it now and as it still has a guarantee on it, we have log a request with Makro Polokwane to repair the fridge on the 14th instant. The person assisting us, informed us that somebody will call us within 2 days. No calls received and we phoned Makro Polokwane again, only to be told that there is a 3 year guarantee and that they will contact us before then. I then phoned their Head Office on the 18th instant and they informed me that they will urgently look into this and come back to me When I followed up with them this morning, they informed me that they cannot find any request for this repair. What should I do now?
