Branch Manager not getting joy from Supplier

Good Day. I have been having this problem With JD for the past 3 months were the Branch Manager has tried his best to help me but has not been helped by the supplier Grafton Everest. I have posted a complaint about GE and to date received no feedback from anyone at EV. I have been a customer with Jd for over 10 years and have a excellent relationship with the branch manager. I purchased a Grafton Everest lounge suite for R24 000 about 2yrs ago. The 2 seater has collapsed on one seat were the springs have given up and the 2 seater 3 seater and 1 seater the leather fabric has started to crack all over and looks terrible. If I only knew that Grafton Everest service and products were like this I would have never purchased it. The product is still under warranty were I have taken extended warranty but have paid extra and not received the service. If I wanted a cheap set I would have purchased a set from Mayfair. I do not recommend anyone to purchase any of GRAFTON EVEREST Products from any retail stores. I hope I get help from someone senior at the JD group because the Branch Manager has tried his Best. Cheap and Terrible service and products from Grafton Everest !!!
