Unfixed washing machine - Consumer Complaint for OK Furniture - Head Office

I bought a washing machine at Ulundi OK Furniture in June 2019, while I was using it in September, the spinner wasn't working properly I took the matching back to the shop at Ulundi OK, they took my details on the slip and told me to return back with the machine and said they will bring the defy team within a week to look into the problem at my place of stay I shouldn't leave the machine at the shop,I then went back home and been waiting for the defy team but up to today has not got any call from the defy team nor from OK furniture retailer, but he promised me that there won't be any mistakes he will be the one to ensure that the defy team come to my house and he will keep calling them. So now what should I do?
