Threatened to pay wrongly charged payment by tatadocomo

Hello Sir, I got a call from One of the person from Delhi saying that he is Advocate from Tata Docomo and Arrest warrant is issued on my name for IPC 420 and IPC 406. He said he is in the Police station and logged a Fir and I have to be present at Police station and saying etc etc. He forced me to pay 10,298/- rs immediately by threatening otherwise I have to face so many Legal things etc. So as a Normal and respectful Citizen with clean records till date, I was scared and have to submit that amount. The Amount that I have Payed is wrongly charged to me from TATA DOCOMO for Broadband Internet Connection which is sent for 6 months in advanced and I have already made several complaints for the same to customer care, but no solution. Suddenly today this incident happened. [After the payment and some inquiry and research, I felt this was a fake call and just to scare me so that I Pay] Also after 2-3 months TATA DOCOMO discontinued our service as well, so there is no point of paying this much of amount. So could you please suggest/provide me the solution for the above matter. Name : Tushar Jajodia Circle : Ahmedabad (Gujrat)
