Bad service

I need urgent assistance as the service I'm getting is terrible an exchange was done on my bed a week ago,when I got home I noticed it was the incorrect product delivered I immediately called the driver which was very accommodating and advised me that he noticed that the mattress was different but he could not voice his opinion as he was not sure of the arrangements with the warehouse ,he then advised he would get the manager from the warehouse to call me well till today not a single person has contacted me ,I then called the very next day the lady at the warehouse took my details and advised I would get a call,well nobody called ,I then called the following day a lady answered and said let me put you to the relevant department after holding on for almost 10 minutes the call gers cut ,I then called the shop in West Street Durban numerous times even their phones don't get answered well even messages I left for Ntokozo to call me never did ,all I need is for the correct product delivered to me and its so hard ,how do we deal with this company going forward ,well for me with so much *********** staff I will not deal with bradlows again ,if they cannot deliver the correct product I would like a full refund and I can go to a place that will welcome and appreciate a client.
