Tikona — Harassing calls from this company saying as advocate from delhi

I had requested for termination in the month of March 2015. But due to the customer care negligence who was not able to take my request nor had the patience to understand what im trying to say regarding the service they ignored/forgot to terminate which im not aware of. Again in the month of july i got bill saying outstanding of 1124 saying i paid that bill also so that i can close the connection completely without any issues. After all this high drama i got a call from [protected] saying advocate from delhi and i have to pay amount of 300 which i dont know when i used after full n final settlement . i went back throghu emails and found that this amount was late pay ment fees 1. i havent used the service still i paid a months bill, second on top of that these late payments. i will never ever suggest this service to anyone .Such people should be punished everly for looting money from innocent people. what rights do you have to call from delhi and ask me to pay money for which i havent used. I know these people saying advocate/lawyer all are fake. i will take this seriously. thought 300 or 1000 rs seems normal to you but not for me.
