[Resolved]  Simplilearn — Unethical behaviour

My mail inbox is getting filled with simplilearn ads. While checking one of simplilearn mail, it directed to their website and opened some chat box. I started chatting and enquiring the guy about my doubts. Instead of responding my queries they keep on asking my mobile number. I informed that i cannot provide mobile number as i am not allowed to carry mobile to office as per office rules and provided my mail id. They are trying to frighten me through continuous mail saying that they are removing my request etc., this created panic to me and could not able to concentrate on work. Please help.
