Extremely poor service from Better

I made a cash purchase of a couch from your Silverton branch from Betty Sibeko (who never explained the return or exchange policy and just wrote that the couch has a 6 month warranty) end of June, it was delivered in July after weeks of waiting and I complained that the couch was of sub-standard quality and that I will bring it to the store for a refund. Unfortunately, I was hospitalised for two weeks and I welcomed my baby daughter then. I call them now to collect the couch so I can get my refund and Betty Sibeko says that they can't! She says that on the back of the invoice the return policy is 7 days and nowhere does it say that for furniture.

I need someone to please collect this couch so I can get my refund.
