Bad quality and bad services

I bought a wardrobe from mattress and couch on the 13th of feb and I was told the delivery will on Wednesday the following week.the guys came and I wasn’t impressed with the installations ,the hanging rack is falling off and I can’t hang clothes .I showed them before they left ,the told me that there’s nothing they can do as it comes like that.I called the store while they were still here and they said they will replace the rack tubes .till today they have been giving me excuses.and the wardrobe is strongly smelling of a paint ,It’s bad the quality is also poor it can break anytime Almost all the nails weren’t used for the wardrobe they said it’s the remaining nails but how possible as none of specific one weren’t used . I’m stuck with a wardrobe I am not using I told them to fetch it I nolonger want it .they said they can’t refund me . The person who was assisting me Sam gave me email address and said we won’t refund you .
