Entitled disrespectful employees vat Game canalwalk

I recently bought a gazebo at game store in canalwalk when I opened it up to use ,tue entire gazebo fell apart resulting in cutting my nephew on his arm the gazebo was broken at every angle I then contacted the store at got to no response I then took the gazebo to the store and was turned away on 2 separate occasions I was then told by one of the employers to contact the supplier which I did and got assistance immediately after endless emails and calls I was advised by massmart to take the gazebo back to the store for the 3rd time and get a full refund apon doing so my experience was a nightmare the disrespect from the staff that assisted me and being questioned if the gazebo was really bought at their store even when I provided proof of purchase they continue to keep me waiting for more that 30 minutes the employer that was appointed to assist me refused to meet with me the lady kept having to call him telephonically to sort out the situation as so had no clue what has transpired the insults he was saying on the phone was so embarrassing as other customers was standing in the line could hear everything as he was on loud speaker when the lady that was helping me realised I heard the whole conversation disconnected the call . I have filed a complaint with the national consumers commission ombudsman .
