Tata DoCoMo Mobile Services — Nuisance with OBD calls from Tata Docomo for postpaid connection

Address:

Chennai, Tamil Nadu

Iam getting daily OBD calls from Tata Docomo asking for postpaid connection. Iam a vodafone customer and already having potpaid connection. I have told many times and alomst for more than a year I am getting this OBD call from Tata Docomo that I dont want any such connections but still daily Iam getting this call which disturbing my work and personal life. And moreover when I said "please dont call daily" the person who called me named "Padmanaban" is absuing me in bad words which is really not tollerable. I want an immediate action on that person and also on that company(Tata Docomo)calling for promotion through OBD calls. My details: Name: Ravikanthan Mobile No: [protected]
