Wesbank horrible customer service

I app**** for business finance via Wesbank on the 4th of October, today is the 9th of October and I still don't know if they even received my application. I manged to find telephone number of the office where the person who send me the application forms is working, left him a message a few days back and I was told that he will phone or write me a an email, but nothing yet. I send my business banker an email which she responded to and she asked for more information which I send to her, but then she never read her e-mail untill I phoned her late the following day. I phoned FNB's business desk, my personal business banker, Wesbank client service and the guy who send me the email, it is day 5 now and I don't even know if they received my application. It is an urgent sale that I don't want to miss because otherwise they will sell it to somebody else and my time is basically up now...so sad about my own bank letting me down
