Tikona — No connection from yesterday and being abused by the staff

Address:

Bhandup, Mumbai

My internet is not working from yesterday. When contacted customer care, he asked me to do the rest of the remaining payment then they will start my service right after the payment.
After payment, when asked them to restart my services, their staff name upendra from thane mumbai used foul language.
After warning him not to use foul language, he started abusing me.
Called customer care, waited almost an hour on ivr to talk to customer care but no response.
I want an immediate action to be taken on this issue and on the staff named upendra. I have the recordings of conversation.
