Grafton Everest 3 Piece Sabre Lounge Suite

I purchased a 3 piece Grafton Lounge Suite around the 30 March 2015, which I paid cash for. This lounge suite was only delivered to my place on the 9th April 2015. I had to contact them on several occasions until finally lodging a complaint with their customer care center. After having the lounge suite for 2 weeks, I found that there is a flaw in the fabric which is causing it to rip apart on the backrest. I have contacted Morkels and Grafton Everest and am getting no joy at all. I was told that Morkels have a 5 day turnaround period. My complaint was lodged on the 30 April, it is now 8 working days that have passed. The Manager and the Sales person Lesley, have promised to \check"and get back to us"
