Over payment to MFC and refund takes 5 working days!

Good day

My account WAS in arrears however a debit order of R2264.39 was debited from my account on 5 June 2019. I then also did another EFT for R2700 in order to get the account up to date. There was then another debit order of R2524.94 debited from my account on the 7th of June after I advised MFC that I have paid the account up to date yesterday 6 June 2019. I have spoken to the call centre and was just advised that I need to send the proof of payment of the R2700 which is already reflecting on the account (not sure why this is necessary then) and request a refund for the balance but they will only be able to check this after the debit order for today is reflecting on the account. And to put the cherry on the cake, I was told the refund process takes 5 working days. They weren't very helpful. Please refund the over payment back to me.

Thank you Yolandi
