Westbank and FNB. Pathetic car finance service

I've been trying to get an application with Westbank vehicle finance to be done and I've had no feedback for a month now. Everytime I call in to see I keep receiving and error code when submitting my application via the online portal both with Wesbank and fnb. When I went in to FNB for assistance they said can not help hence cause that's part of Westbank and not then when I call both fnb and Westbank and explain my issue they both say email your queries and we'll take it from there but nothings been done after that. I'm so frustrated with endless calls, numerous visits to the bank and email. I've been a loyal fnb customer and didn't think that IL struggle for help like this. I've missed buying 2cars cause of the hold up on my application.
