NO FEEDBACK, DEMAND REFUND

Purchased a Grafton Everest lounge suite and TV less than a year ago from the Northgate branch. The lounge suite has reclining parts on the three seater and the single seater. The material and sponging started to collapse on the foot and leg rest parts as well as the stitching pulling apart. I called to log the fault with Bradlows. the Couches were collected the 4th of January 2019. I was told it would take 2 - 3 weeks for the repairs. Reference number MO-GRAF-***.I have had no feedback from anyone. I have called JD Group head office and logged a compliant, TWICE. NO ONE has bothered to call me back. The only response I receive is that the supplier has a back log because they were closed over the festive period. How is this my problem? I Cannot wait any longer for the repairs to be done as it has been long enough. Is it my fault that I was sold a sub standard lounge suite that collapses less than a year of purchase? If I do not get feedback by latest close of business tomorrow I will be going to Bradlows Northgate, return everything and demand a complete refund and reversal of sale. This is absolutely ridiculous and I cannot and will not wait any longer.
