Harassing Marketing Calls

What do I have to do to get Miway to stop with all the marketing calls? I received 5 calls within the last 4 days from Miway – that excludes the calls I’ve received the last few months. I have never had an interest in any of Miway’s products and have never utilized any of their services. This is pure harassment. They simply won’t stop calling, despite continuously blocking their calls. I have never consented to my number being used for marketing purposes – which is of greater concern and given the fact that I have never either been an employee or client of Miway, where did they obtain my contact number from? If they don’t stop with all the unsolicited marketing calls, I will obtain a restraining order against Miway because I am sick and tired of being harassed! I am not interested in your products!!!!!
