The Brick review: Poor quality sterling couch and chair

On Aug 5,2023 we purchased a grey Sterling power sofa & chair plus the full 5 yr warranty It was delivered to our home in Carstairs on Aug 7,2023. Within a couple days we noticed the left side section of the couch was starting to separate. The right side there was a gap of less than 1/2" where the left side was 2". We took videos of the couch and returned to the The Brick in Olds where we purchased the set. We talked to Tricia our sales rep and emailed her the videos which we had taken which she forwarded them to her boss Gillian Kervin. We didn't hear anything from her for a few days then we had to contact her which then she proceeded to tell us that there was nothing wrong with it that the separation was normal. We had in the mean time went to the The Brick in Airdrie and viewed their couch and there was no separation. She informed us that it was up to us to get the couch back to the Olds location where in the warranty book it stated if we are within 40km a technician would come to us ( we are 23km away), and when we questioned her on this she informed us the tech does not come to Carstairs. She informed us that we would have to pay for the delivery which as seniors we could not possibly get the get the couch there on our own. She then said there was nothing she could do. Mean while the right hand side cushions on the couch started to sag which is my husbands side and he is not a heavy man. We sent videos to Gillian and she said this was normal (After 2 weeks NOT). We then had several arguments with her that we wanted something done. Finally on Sept 18 they sent a truck to pick up the couch which we were to understand was going to Calgary to be looked at instead it went to Olds where we understand a tech came to have a look at it (Neither Gillian or the manager was there which we had specified we wanted a video and a written explaination we got nothing). Gillian contacted us on Sept 23rd and told us the tech didn't find anything so we informed her we would come to the store on the 26th and would like the manager there. When we arrived they again said there was nothing they could do we did not accept this decsion as now after a could of weeks my husband sitting on the chair it too the cushions are sagging to a point he has to put extra pillows so that it doesn't kill his back. The manager told us he could see what he could as quickly as possible. I contacted Gillian on Wed Oct 4 and she had no news and was going to get the manager to call us still no word. It is now 2 weeks and no one has contacted us. We would like a full refund NOT a in store voucher. If we don't get any satisfaction our next step is to contact the BB and a lawyer.
