No money for refund

I have been trying to get my money back from this place for over a month now. The car was paid for until 11 October 2019 but we returned it on the 8 October 2019. All service that we received prior to this was brilliant until they have to return my money. I guess the courts will have to become involved. It is so sad that a promising business cannot cope with their own business principles. I have sent them numerous mails requesting the refund of my money and they dont even bother replying.
