Crossroads — Abusive language from Executive from Crossroads

I have been receiving unsolicited calls from crossroads frequently even though I have told them on many occasions that I don't own any car. Today one lady named Anjali (Telephone No. [protected]) called on my office mobile phone and abused straight on my face. I am a Government employee and when she called me I was on my duty. Kindly take action against your executive else I will register a written complaint against her with Delhi Police and Ministry of Consumer Affairs. Kindly send compliance report of the action taken against her ASAP.
