Tikona making threatning calls

I unfortunately was one of the customer of tikona broadband. It has really poor service and internet doesn’t works. I used to work less and make complaints more to tikona customer care for resolving the internet issue. Pissed of from the service i requested tikona to disconnect the service and they did so and also they have took their equipments away. Now from few days i am getting some calls from delhi legal department and civil court stating they are so and so advocate I can’t recall the names and they say under this session you are liable to pay so and so amount to tikona please pay other wise enquiry will be done. Today also i got a call from Mr. Devraj joshi according to him he is a advocate and his number is ‭+91 8441-062135‬. These people doesn’t have sense to speak with people, I know they are not calling from court because court doesn’t make calls to people just to inform them that please pay the bill and court directly send notice to the one who is responsible. But we need to get rid of this people and fraud companies like tikona as they are not good into service insteaf they threat their customers. This is legal gundagiri and some reaction is required for their this action.
