Worse Service Ever- Worse Quality of Goods

I went to Lewis in March bought a lounge suite and new television. When the TV was delivered it wasn't what i wanted and went back immediately. I then changed the TV and was advised that it will be delivered tomorrow (Monday) Monday came and went. After almost 3 days i was advised they don t have stock this after them telling me the is stock they trying to find stock. The a week lately a TV is delivered without a box and i asked the delivery guy what is this a Demo and he said I was furious do they really expect me to pay full price for a demo TV where all the functions arent working. i contacted the store the next day and was told they are getting stock month end. I sat with a TV taht wasnt working to its full potential for more than month and paid for it. Eventually they replace the TV. I then let them know that the couch i had purchased is stitching is coming loose and it is sagging. They advised they will collect and send it away to be fixed it will take 10 business days. It was more than a month gone and this point my account was paid in full. Couches comes back on EID Morning on top of it and its worse than ever i let them know and a month later still nothing being done. I went to the Store Sunday and the manager promised to get back to me Monday instead she gets back to me Tuesday telling me she will provide me with feedback before close of business Tuesday it Thursday and still nothing. How is it fair. I paid for goods that i am not happy with and no one gives a damn. Pls PPL don't buy from Lewis
