Utterly disappointed

The worst service I received for the whole year. I am very disappointed with the service I received from HomeChoice. On the 20th of September I made a purchase for an amount of R1002.39 and I was assisted by one of the sales agents. On Monday I received a call from the delivery guy saying he is at my address in PE. I have no idea where did they get that address from, as I live Johannesburg and have never lived on PE. I am utterly disappointed in this company. When I ask them to cancel the order and refund me my money, they NOW asking for proof of address. Why did they ask for this before taking my money. I have to be inconvenienced because of their incompetence.
