REFUSES TO TAKE ME OFF THEIR DATA BASE & HARRESSME

I closed my account with the above company a while back. The call centre agents still call me every month and even over a weekend. After numerous emails and speaking to the team leader instructing them to stop harassing me and to take me off their data base, they continue with their harassment's. I get called during working hours and get called by my first name as if they are on talking terms with me. <br> I am going to take this further as my privacy and time is being wasted despite numerous attempts to get them to stop.
