just CANCEL the application

I app**** online for a personal loan, it was preapproved. When i called in to the call centre they advised that i had two profiles that had to be merged which can only be done in the bank. Well i get to the bank and the withdraw the online application and do a new one, all to have the same issue. I then called the call centre once again to redo a third application and they now say i have to go back to they bank and cancel that one which the branch did. But for some strange reason now the call centre cant continue with a FOURTH application because the bank has not withdrawn theirs. Which they did and i have proof of. So please just cancel it for me. Why the hassle for goodness sake??? Dont falsely advertise fast and efficient service! When you are capable of neither!!
