Phone calls in Goa disconnected automatically

In an indication of the harassment domain investors face in Goa, a domain investor found that on 10/9/2015 at around 7.30 am , the phone call which a family member received was disconnected at least 7-8 times within fifteen minutes, It clearly indicated that phone calls are being closely monitored, by indian intelligence agencies, who are then misusing the sophisticated monitoring equipment at their disposal to disconnect the phone calls to harass the domain investor,
The phone calls to both the landline and mobile phone of the family member were disconnected repeatedly due to no valid reason at all, indicating that tax payer money is being wasted to harass harmless civilians.
Why has harassing the domain investor become such an important priority for local intelligence agency officials,do they have no other work, other than terminating phone calls.
