I REGRET TAKING A CONTRACT WITH VODACOM

Dear Peter, My issue is still not resolved by Vodacom instead they making it look like i'm the one who was ending contract with them but the phone was faulty and it was return within 14 days of receiving it. The phone was collected by RAM on the 13 April 2021 because it had a faulty speaker .They told me they will cancel my contract as the phone was faulty .They keep debating the money since April until July 2021 while the phone was return to them.I was not using their data neither using the physical phone. How I'm suppose to pay 8000 while the problem was on Vodacom's side ?I'm not using the phone but i must pay 8000 how? No alternative was given to me by Vodacom.They didn't repair the phone or suggest to give me a new phone .i was the one who kept on following up on them with the way forward and without giving any proper resolution on the issue but since they have cancel the contract i must pay 8000 for something that has been return to them.how?
