Vodafone India — Bad language used by Vodafone operator

Address:

Bharuch, Gujarat, 393002

This is regarding the complaint against one of your Vodafone operator.
The male person called me at 5:22 pm on 01/05/2017. Number is [protected].
The operator has introduced him calling from Vodafone and told me to have an offer from Vodafone. He asked me "Is it good time to talk."
I was bit busy and told him to call next morning at 10 am. Some sound came from his end saying, "Ok Ma***C***d." 2 times.
Is this a customer will hear from your end.
Take the action as early as possible.
