Don't buy from Lewis in Randburg

I bought a dinning room suite cash. It was delivered the next day. Upon delivery the guys refused to assemble the table saying it's not their job. I called Lewis the next day and was informed they will send someone.. never happened. I called again..a supervisor by the name of Stanley said he will come himself...he later called and said it's late now, why don't I assemble it myself? When I call in I am told he is on the phone later he is in the stockroom? I regret paying cash maybe they were going to more professional if I had taken the furniture on instalments and defaulted on payment?? They are unprofessional! Don't buy at Lewis!
