The Brick review: King mattress set

Where do I even start. This has been the worst customer service experience I have ever gone through in my life. Last week, came in to purchase a king size mattress set. Found a mattress that I liked and was told by the sales rep that if I wanted to be able to exchange the mattress I would have to purchase the mattress protector as well (which is about $180). So I ended up purchasing it as well in case I was not satisfied with it. Ended up not liking the size of the king when I got the mattress delivered and decided I will request to exchange it for a queen size. Got to the store again and was told that the remaining difference would only be a store credit, which was NEVER told to me by the representative when I purchased it. So I would still have to pay out of pocket so that I can have an extra 300 in store credit that I will never use. Then I got told that the mattress protector is final sale and therefore they will not be able to take it back, and that I didn’t have to buy it as I had 90 days to exchange anyway. So what i’m hearing is I wasted my money buying an overpriced mattress protector for no reason. The representatives at the store are refusing to help me in anyway and basically just telling me there’s nothing they can do. Absolutely will never shop at the brick again and would recommend that no one wastes their time and money shopping at this store either as they don’t seem to care about their customers.
