Pathetic service Wesbank

I am pre approved for car finance, i submitted my documents last week thursday to Wesbank private finance, up till today i have not received a call or sms too state that my applications been processed it only when i call the call center which takes over 45mins too make contact i get told too submit my documents… now that i have submitted my documents i was told i will get a call in 48 to 72 hours …. surprise after 72 still no call , when i call the call center for feedback , i get told the application is with the credit department and must forward payslips in pdf which i have done , the lack off communication is pathetic, i have been a loyal customer off FNB for 25 years and i am seriously considering moving …. to this date the seller and i have not been contacted, and i might lose the purchase off this car due to the seller not been contacted yet
