Car Payments not going off, along with EFTS

I have had countless issues with Standard Bank this ENTIRE month. I have phoned them without fail, at least twice a week. I have even had to go INTO a branch to sort this out. Each time I am told that the problem is not on their end. When i eventually went in, it turns out the fault was on their end. I was told my payments would go through as usual. I watched the consultant who helped me, eft an outstanding payment to Wesbank for me. I now get an sms to notify me that it hasn't reached Wesbank. This stage is now reaching critical. Each time I am NOT helped. When I raise an issue to be fixed, I am always told it will be fixed and a few days down the line I notice that the same payment has NOT gone through. This does NOT seem like a hard thing to do. The urgency of this matter has currently reached critical and this is starting to affect MY credit rating and it is affecting my job since I am constantly on the phone with a useless bank who refuses to help me.
