myway marketing

I have been contacted like once a month sometimes 2/3 a month by the marketing company's for insurance with mi-way I don't own a car even. I told them on number of times to remove me of the listing. after i get angry and threatening them it stops for a while and now its starting again. If i block the call they try every day. they are just as bad as the ******** that trying to convince you to take there product. Surely there are a database that lock the calls and they can make don't contact after the first time they speak to you.
