Vodafone India — Abusive Language Using by collection agent

Dear
I am having 2 vodafone connection [protected] & another one [protected] generally used by my spouse in home.
Both the number i am using from last 10 & 5 years almost.

As communicated by vodafone about my outstanding amount for December 2014 I had paid the Bill of Rs. 700 against [protected] this number on 1st of this month.

Now on regular basis Someone from Vodafone collection agent address himself as Mr. Nandi calling us from [protected] to my wife and using very unrespectful languages. Which she felt highly insulted & harrasment.

I Have informed the entire matter to their Collection Manager of vodafone through mail however haven't received any communication against that.

Still every day collection agent calling her & using abuse language without mentioned any reason of that.

Sir here i am requesting you help to stop such kind o[censored]nethical calls without any reason.
