No interest in customers

It is now almost a month since I app**** for vehicle finance which was approved online the day of my application and then formally once all documents were supp****. I have to keep following up on progress, the marketer keeps sending documents to the wrong address and not following up with the seller if they received it, I had to figure out it was sent to the incorrect address and then send the documents to the seller. They ask for me for documents I already submitted. The marketer told me he will be back in the office on Friday afternoon to sort this out and he wasn't. My so called private banker says she can't help. Just can't win with this. Customer service is out the window with you guys. No urgency to make a sale, no interest in assisting a loyal customer that's been with you since 2012! Really considering making a move after this pathetic experience!
