Misinformation, poor and bad customer service

The car that I financed with vw finance was paid up on the 28th July 2021, but unfortunately the monthly installment still went through. I called vw finance on the 3rd of August 2021 to request a refund, I was advised that it will take up to 7 days to reflect on my account.

I called again on the 13th August 2021 and was told that the payment was made on the 13th August 2021 and when I checked no funds were refunded to my account. I called on the 14th August 2021 and was transferred to Michael, a team leader after I was told that there's outstanding information that it's needed from me. I refused to wait another 7 days or more and he promised me that the funds would be refunded on my account on Monday, 16th August 2021 and nothing happened on the day.

I called again on Tuesday, 17th August 2021 and was advised that the money was refunded back on the 17th August 2021 and when I queried that and told them that I've been told that several times, the guy who assisted me said that it will take up to 48hrs to reflect on my account. I asked to put through to Michael and the guy I spoke to refused and after persuading him, he told me that he's gonna check the availability of Michael and kept me holding without giving any word of whether he's succeeding or not until the line got cut.

In all of this struggle, no one bothered to return my call and ease my frustration, I have been the one calling and everytime I was given incorrect information by the call centre agents who assisted me. I am so much disturbed at the poor and appaling service I received from them. I've been financing my cars with them since 2006 and I don't think I will ever use their services again or advice any one to do that.
