Wesbank not settling finance, after funds paid over a month ago.

Early September I was in a car accident. It was written off by my insurance. I informed Wesbank immediately via the website. On the 21st of September Discovery paid the settlement to Wesbank and this is where all the problems started. Up until now the car still hasn't been settled. For almost 5 weeks I have send the proof of payment that I received from Discovery to Wesbank so that they can see it was paid. Two instalments was taken off my bank after Discovery paid the settlement. Every time I call Wesbank, I am informed to wait another 5 days. After 5 days, I call again and are told to wait another 5 days. This has been going on for over a month now. I cant finance a new vehicle until this is sorted, I am without transport and Wesbank is doing nothing to assist me.
