[Resolved]  Tikona — threat calls from tees hazari court to recover bill I haven;'t used

I and my friends used tikona services in the year of 2015, their network never worked and was always down still we made the payments and asked them to cut the connection.1st the didn't cut and charges us more bill then after a final payment of 2000 their agent came to cut. But after that still we are receiving threat calls to pay the bill. We had asked them to cut the connection in dec 2016.
And still i am receiving threat calls from teez hasari court that a case will be lodged against me in next 30 min.

Please help.
