Very poor quality for 'Grafton Everest' Lounge Suite

I Bought a Grafton Everest lounge suite just over 2 years ago. After a year the leather started cracking. You guys collected it and repaired it. After a few months it started deteriorating again. You guys acted again a few months ago. Now the same 3 and 1 seater's leather started cracking again. I tried calling your call center but the agent just cut my call while I was speaking to her. It's always a nightmare trying to get assistance from you'll. Please can somebody contact me to discuss getting this issue resolved. Its frightening how a lounge suite I paid over 20K for is cracking for the 3rd time in less than 3 years. The account is on my wife's name ID ********** 041084
