Harassing phone calls for non-existent home loan

First of all, I am not a standard bank customer, nor do I have any accounts open with your bank. But I have been getting constant automated messages/phone calls telling me to pay a home loan which I DO NOT HAVE. Upon calling the number ***, I twice asked 2 different people to have my number removed. But obviously nothing has been done. I'm getting at least 5 phone calls a day, it is extremely annoying. Please remove my phone number from your system
