Cold service

I bought a Defy microwave 6 October 14, and it broke 30 April 15, i took it back and they told me they will fix it, i get a call from this lady to say it's ready, and i tell her i'll fetch it tomorrow, i get it from her and she can't even tell me what was wrong with the thing, i get home and warm a bowl of soup then the microwave just goes dead, i take it back again to the store and the lady books it in again for repairs, a day goes by and i hear nothing of her, i contact the store and they tell me it's ready for collection and it was repaired in store by the technician, i take the microwave plug it in warm a vienna and guess what it does'nt go on again, the next day i go to the store again i ask for the manager and he gives me a very 'warm welcome' i explained to him the situation, he tells me it's after 6months they will repair it and Defy is not at their store, but it doesn't seem like the manager is interested in helping or getting a solution, when i asked him what's going to happen now he tells me \ just told you"it's shocking how this man can be a manager when customer service isn't priority to him"
