Bad service

I had a case with Standard Bank which ended up including ombud because of a code 3 vehicle they financed without receiving a natis till date which they don’t have…fast forward ombud and Standard Bank agreed that my contract should be cancelled which happened and I should get my money back. Now that they need to reimburse my money the gentle who helped now all of a sudden wants changes the agree after agreeing with ombud and Standard Bank that I should get my money back. I only used the car a week and a couple of days and still a year later after cancellation I haven’t received my money back… even the guy who I’m supposedly suppose to be talking to doesn’t take my calls or has updated me on the case! I’m really disappointed with their service even after an agreement with the ombudsman this really sucks
