Bought damaged goods, no help from store

I bought the pram at the beginning 2015 maybe around Feb sometime at cape Gate. Not long after the pram could not close and was sent for repairs. I took it to N1 city and they sent it to the supplier. I received a loan pram to use. 3 weeks ago the pram broke again this time i said i wanted another pram and was refused that. I spoke to Clayton at Cape Gate and he escalated to the call center. i never received a call. i went back to N1 city branch and they said that the manager had called to say i might come. After standing for almost an hour in the store i was told that the area manager said there is nothing they can do. They wanted a sales person to try to fix the pram,. Keep in mind the pram has a 1 yr warrantee and they refused to send it to the supplier to fix. I refused to let anyone tamper with it. the service was terrible and the fact the a pram breaks in various parts within a few months apart is crazy. My baby cannot sit in the pram as she cannot be strapped in which is a safety hazard. these people take your money then refuse to help when their stuff breaks. i want something done asap. I have a pram i cannot use. Extremely unhappy!!!
