Medlife — Mental harassment is being done by computer calling on behalf of the company

SIR,
I am HIRANMOY MONDAL.MY MEDLIFE ID IS [protected].
Few many times I called the helpline number and requested to activate the DND service.But that service has not been activated yet.
I am constantly being harassed by phone calls from the company.
This is the last time I have emailed you if the DND service is still not activated.I will be forced to complain against you in the consumer forum.
Hopefully you will not take me in that situation.
This is my dedication to you, please release me from the pain of burning.
