Not a very satisfied Customer

So last year October we bought a new Edblow Mattress at the Lewis Store in Krugersdorp everything was fine with the Mattress in March the Mattress started to give us problems and we went to the store just before the Lock down to go and report the Faulty Mattress and the Sales person who helped us promise that they would deliver the new Mattress the very next day... So the Lock down kicked in and they could not Deliver the new Mattress. So when Level 3 of the Lock down started to ease and delivery's could continue we went to the same Branch to go and enquire regarding the delivery of the Mattress. Only to be told that the Warehouse does not have stock and that the sales Person who sold the Mattress to us will call us in the next two days to give us feedback.... So we waited and nothing happend. A week later we went to the shop again to go and find out what is going on and the story they gave us was that their Rep said that that specific Mattress does not get Supp**** anymore by their Warehouse and that they would call the other Branches to find out if they got any in stock and that they will give us a call back the next day. So we waited for the call the following day and nothing. Last week Friday I gave the Store a call and spoke to the Sales person handling our our Complaint and he told me that the Other Branches does not have that specific Mattress. He will see what he can do in order to exchange the faulty Mattress and that I should give him a call back on Wednesday 22 July 2020. The thing that is the most Frustrating at the moment is that there"s NOOOOOOOO!!!!!! communication from the shop to me as the Customer and I need to phone them every ti,e to find out what is the story... They were quick to take my money but when it comes to Customer Service there's nothing... One thing for sure I wont be baying anything from them again due to the lack of service I received.
