Sir
I have been receiving threatening calls from someone pretending to be a policeman and someone pretending to be a lawyer from rcom about recovery of some amount they claim i owe to rcom.
I had an internet connection with rcom
No. [protected] few years back my plan was 300 rs per month when reliance changed my plan t0 1500 per month without information i requested to change my plan when they refused to take my complaint i told them to stop my my connection.
Now i have received a mail from a lawyer named manoj som. Kindly tell the company to stop harassing me.
