Bad costumer serves

I have bought a launch sweet in Feb 2018 and until today I have made use of the two seater in total two months of the twelfth. On the 1st occasion I have requested the store to collect the couch for repair work it took them two months to collect it to be repaired. They phone me to arrange on the Wednesday to collect the couch, I then arranged a days leave to be at home then they did not pitch to collect the couch. When I phoned the call center they told me that the day is not over they will still come @ 16:45 they only came the Friday.

I then received the couch back one month later. Two weeks later exactly the same problem occurred I then reported this to the store and after 3 weeks of not getting response from them I reported it to the call center. Again they arrange to pick it up on Wednesday and again I had to arrange a days leave. Again they did not pitch up the day arranged and only two days later. Two weeks later they brought the couch back and while inspecting it I found that it was still not repaired and had extra damage on it that where not there I then send it back on both occasions I have requested for a new couch as this issue is a lengthy issue that looks like it cant be resolved. No direct contact from any management position was made to me to resolve the matter after numerus attempts.
