Makro and Defy giving me a run around.

I have sent from pillar to post by Defy for the past 3 weeks. I bought a stove from Makro in February. Stove was fittend and was working fine till beginning of June. I began giving error messages and jamming. I called Makro and they logged a call with Defy. The technician came through and said there computer unit is faulty and had to be replaced and was going to order it. Its now been close to 3 weeks and no word from Defy. I have on many occasions tried to call the service centre but the phones just ring and no answer.

I am now thinking of returning hte stove to makro and demand my money back.

So frustrated.
