Poor Customer service

I made a big buy account purchase for a L- couch at the branch in East London. I asked the store to order a couch which the day bed will be on the right, as the one displayed in store. Upon delivery the day bed was on the left, I asked the store to fetch this couch and deliver a the right couch to me. Two days ago the manager of the store called me to come and fetch my couch. of which I refused because I had already paid for delivery when they delivered the wrong couch. The sales man had agreed to deliver and assemble my couch at their own costs. The following day I then called the manager (Marcia) to ask when my couch would be delivered, she then promised to call me before end of business, I am still waiting for that call. The issue is the account will start deducting money from me on 7 days time and I will be paying for a couch that I do not have. When I call customer services I am told they have a turnaround time of 7days, which is useless, as they would have already deducted my money.
