Disgusting service

I bought a wardrobe on the 26/04 and in the shop they told me someone will come and assemble it within 7 days till to date tht person didn't come and every time I call the guy he lie to me saying he will come the next time, they service is very poor and disgusting, I regret ever but from them and the guy that supposed to come n assemble the wardrobe is not professional he doesn't know how to talk to customers
