Bad service from MFC

I am an existing customer with MFC for 20 years . I recently app**** for finance on the purchase of a second vehicle .<br> They did my application and screened for affordability after running to and fro to the dealership and back getting all the documents they required , then they come back to me and say we need proof of all the additional income i receive to finalise the application and all should be well . They even told me , i quote \ do not apply for finance anyway else or else this will affect your application
