I took an internet connection 3 yrs back and closed it before around 1.5 yrs - 2 yrs. Today I got a call from(9981708022 - Arjun Singh) claiming that he is calling from Gwalior High Court and informed that they are going to file a case against me and told me to contact the advocate(9981710256 - Alok Sharma) to know more about it. I talked to them boldly and I had a doubt that they are not from HC or legal dept/advocate. They also told that I have to pay 50000/- as penalty. It is not possible according to Indian law. You can pay only 5000 and get bail for criminals. Probably they are from collection dept. Just talk to them boldly and ignore them. Tell them that you have already paid your bills and tell them to do whatever they want.
