Sleeper Couch order confirmed with no delivery

I asked to use my mother's Homechoice account to place an order. That was allowed as I will be making the payments. A sleeper couch was on special and I was called to place the order after approval from my mother was received telephonically. I think it was a Noluyanda that confirmed the order. My mother (Account Holder) was called back to say when the delivery will be made. 2 days later, I called in to make another order for a kitchen unit. A few days later, my mother was called back and told the unit would be delivered first. When asked why because the couch was ordered first, no reason was given. 2 weeks later, I call to make a follow up on the delivery of the couch, I am told I am a third party and the account details cannot be discussed with me. When I placed the order, I wasn't a 3rd party. Rafeekah had the worst attitude and slammed the phone in my ear. A month later, still no response regarding the delay of the delivery. Rafeekah's supervisor promised to make a follow up and get back to me and to this day, no word from her. Still No delivery of the sleeper couch and when my mother calls, there is no clear answer as to what the delay is. Please assist!
