BAD BAD SERVICE EVER

I am really disappointed and angry for spending my last hard earned money with homechoice, the way homechoice is treating us as customers i made online purchase for an order worth of R4500 its been like a month now they didn't deliver my order i decided to cancel it its been weeks now their are telling me that for them to refund me my money their courier supposed to return the order to the warehouse which they don't know when will that be so i asked if the courier take 6 months or a year to return the order to you as they didn't even manage to deliver the order to me as promised what should i do. They keep quite or hang up on you. i am really tired to follow this people around my only option is with my bank maybe they will help me get my money bank.
