Pathetic customer service!!

I have a new vehicle and it's financed via standard bank, it's my first vehicle and standard bank has made this experience such a terrible and pathetic one. I needed a new debicheck mandate to be sent to me so I could except it and my debt order can go out, I have been calling the customer service in vehicle finance department for over 1 week and till date no help what so ever, such pathetic services. I have been told since the 30th of May it will take 24 hours it's been over 7 days no phonecall or feedback. So now i still sit and wait for feedback and my first installment is way overdue.Standard bank really needs to smell the coffee and take better care of their customers and new think your customer service staff. THEY ARE PATHETIC AND USELESS!!!
