BAD Customer Relation Communication after Service

I bought a bed there and hardly 5 months down the line, the bed was falling, one of the legs came out and the bullpen is coming off too. My problem is that I have reported this to them for 3 months now and I'm yet to receive assistance ( fix the bed ) nor received communication on progress for my case and when I go to the shop I bought the bed from, they tell me their hands are tight, this is an issue head office has to resolve with the manufacture, I asked for contact number of the highest person to contact or email none of them works, the email just bounces back, I'm appalled by this service - the list they could do is communicate and I'm still waiting
