Poor service

I signed up with dial direct and made sure to tell agent do not share my info for 3rd parties or for adverti*****t or other products as this is my personal number and I don't share it - I had 9 calls so far and 2 calls from car track and other people the only company that took my personal number was dial direct this is an direct bridge of popia the only reason I gave her this number cause i left my other phone at home asked for an team leader on hold for 18 minutes, Albert stated he will remove number from marketing still would like to know how car track got my information they called *** number
