Blake & Associated (Homechoice's Collection Department)

I owed Homechoice an amount of R1000.00. they handed the account over to their collection department which is Blake and Associate. Blake & Associate offered me 40% discount if settled the account. The amount I was supposed pay was R707.38 with the 40% reduction , valid until 31 December 2023. I jumped at the opportunity, paid the R707.38 on 27 December 2024 with immidiate payment. After that they are still phoning me about the payment. I told them I have paid using the 40% discount, they offered to me, I was asked to send the proof of payment. I sent the proof of pay and screenshoted the email and sent along with POP. I was told I need to ask for paid up letter given a whatsapp number, where I should ask for it. The person I chatted with said " we will give it when we give it to you. Today someone called me and said I paid on the wrong account number, I need to pay the remaining amount because I paid on the wrong account number. I paid on the account sent to me by their collections department which is Blake & Associate.
