Stop calling me!

i receive spam calls from you on a daily basis. I installed truecaller which blocks your calls automatically. Now you've taken to call me at my work?! Please remove my details from your system immediately. i dont want any of your products, i dont need any of your products so dont call me. Whoever thought it was fine to call a person's place of work needs to get their head checked. you dont have permission from me to do that, so who gives you a right?
