Homechoice bad service

My experience with home choice is so bad. I bought a feather duvet inner and pillows which was defective, the feathers were coming out and scattered everywhere in the house. When i returned it i was not refunded, iv been calling them for over a month now and they telling me they paid into a wrong account number so i must wait until they recover that amount before geting my money. But this was not my fault because i gave them my correct bank account number and even my bank statement but im still not assisted. They dont even know how long it will take them to resolve this issue and when i call them its so expensive because you hold the line for long
