Very slow response from ***

I've been trying to settle my car since 28 October at 9:41am when I've sent my first email and my second email, after no response on 30 October at 10:09.

Finally on 30 October at 11:47am I got a reply.

On Monday 2 November when I tried to make the payment using the reference number *** as given to me in the settlement letter, I get a message stating that the reference number I am using is incorrect.

So, 2 November at 7:05am I contacted Wesbank yet again, (***) no reply, on Tuesday 3 November at 6:44am I sent yet another email, at 19:30 I've heard nothing back.

Now, the thing that riles me the most, is the fact that in a case of a payment that is not made on time, these businesses are extremely fast to contact you, telling you your payment defaulted, but try to get service, and you need to wait for days.
