faulty lounge suite

A lounge suite was ordered. Delivered on 01/08/2015. The owner Mr Sibusiso promised to return on the monday 03/08 to issue me with a receipt and one of the chairs was not sturdy. To sort that out. The armrests on other chairs sounded like it was going to break. He said he will sort it out. Ive called and left messages for him. Which he keeps ignoring. That is rudiculous business. The arm rests are squeaking. Sounds like its going to break. Mr Sibusiso keeps ignoring all my pleas for his help.
