Harassment from blue credit

I get multiple calls a day from this company. They call you and ask if you about an application of a loan. I tell them that i didnt apply for a loan. They then either disconnect the call or state that they are calling regarding you taking a loan from them. Even after stating im not interested in taking a loan, they still call me, which is bordering on harassment. Their consultants are not professional, as when i asked for my number to be removed, the call was disconnected. Even when i asked them to stop calling me, i was called rude before the call was disconnected. As a contact center employee, if i had to behave on calls like how their consultants behave, i would be fired.
