Airtel Postpaid — Threatening language by airtel employee

Address:

Mumbai Suburban, Maharashtra

I got a call from[protected]. There was a lady who asked me whether I want an airtel postpaid connection. I refused saying I already have Vodafone. She asked why don't I want airtel. I said it has bad network here. So she said, "Yahan mil gaye ho, bahar mat milna" [English: You've met here, don't meet me outside]. This she said with a threatening tone. I want some action to be taken against Airtel, and especially the woman who was talking.
