Not happy with Bradlows service

It’s my first time buying at Bradlows Durban west street but the service I got after they delivered my furniture its unacceptable I reported that my Restonic queen Bed gives me a hard time it’s making noise and when I’m turning they say I must take a video and pictures and I did that they only changed the base again it’s make the same thing they said again I must take videos and pictures I did that they approved to give me another bed but till today I’m still waiting and I even paid R500 last month upfront because I changed to seally brand till today nothing happened I’m still sleeping on this bed and it’s uncomfortable when I phone the head office they say they still busy with my complain till today no feedback and the sales lady who was assisting me by the time I opened an account her name is Jabu she was nice at first but now she doesn’t want to assist if I’m asking she said I must contact head office.
