Sleepmasters Ballito Junction

Worst service ever, my mother bought a king size bed in May and the bed was delivered. In less then 7 days my mother complained that the bed is not comfortable the springs are hurting her. We went back at Ballito junction where the bed was bought to complain, manager that was there was Thuthukani who we told that we want atleast to upgrade we were willing to pay extra so long as she has a comfortable bed but Thuthukani said no she can't upgrade because my mother chose the bed herself. When we went back again we got another manager name Nosi or Nozi if I'm not mistaken we laid the complaint and she said she will sort it out. No communication was made we had to keep going back and calling they just don't care. So we recently went back at the store all to find out there is a new manager once again and that manager does not even know anything about our case. Yet we have even complained at the Head office and the supplies of the bed and seems like there is no communication at all between the store, headoffice and the supplies we are stuck with a very expensive bed which is extremely uncomfortable and they don't want to do a refund, yet at first we just wanted a upgrade which they said we can't do we then said we can do exchange but still nothing is being done. Our next step we going to the court.
