Leave me alone!

I get almost daily phone calls from RCS offering me loans and credit cards. I've blocked so many numbers. I've told people to **** off. What more do I need to do to stop RCS from phoning me???? Everytime my phone rings it's RCS. My phone is now permanently on silent. If this was a person constantly phoning me I'd get an harassment order but it's a business to which I never gave my ****ing details!!!!!

Please for crying out loud leave me alone!!!! I cannot deal with the anxiety of more phone calls
