Does Google's support service work?

I have been sending requests to ask Google to remove my contact number that is appearing on a bank's search results. Everyday I receive calls from bank customers who think that I'm a bank employee. The website that Google used to get the contact number is not an official website for the bank but for a Partnership project I worked with the bank for which I was a contact person. The phone number on the the website was changed two months ago and requests to change the number through Google's procedures has yielded nothing despite multiple attempts.
