Very Very bad service

I'm Johanna my id number is ***.I bought a laptop promotion at Home choice and received the packet in full,the laptop that i bought did not work, i tried more than n month to call Homechoice to take back the laptop,their gave me numerous references but still not picked it up and the faulty earphones, it took them one and a half month to come and collect the stuff and said that i must still pay bill,i understand that,after two months paying for something that i don't even have and used, i waited to months, the lady told me that they're going to replace the laptop and the earphones, i recieved the laptop and earphones today, the exact same way i send it to them, they send it back to me, still broken en still the exact same laptop issue, and yesterday they call me when will i make payment for something that i never used and the earphones only worked 2weeks,im very very disappointed in Homechoice and they still want me to pay for something i can't use..what must i do still paying for something that i can't use
