Terrible after sales service

I have lodged a Hello peter complaint on the 13/03/2018 and then got a call from one of their agents that said I need to pay the postage and send the Vacuum cleaner that I bought through Homechoice back to their Head office in Capetown. I pay my installment every month for something that I can't even used as it is faulty. That was the last that I heard from Homechoice but they are very quick to phone and sell something else. I either want my money back that I already paid since 05/2017 and they need to send a courier to come and fetch the vacuum cleaner and cancel everything. I am not going to buy another vacuum cleaner from Homechoice as this is the second one that I bought and the same thing happened. It is still under the warranty. The service from the agent that phoned me was really terrible and their was no customer service. She just didn't listen at all, she only said that I must send the vacuum cleaner back to Homechoice. As far as I am concerned they can fetch the vacuum cleaner and give me my money back or just close my account and I will go somewhere else to go and buy myself a vacuum cleaner that work. This is the second vacuum cleaner that I bought from them and the same happened.
