Nothing very significant in this penalty "UTM put under 1 month usage cap". Got this message for more than 100 cases in last two years. But not a single message about any further more stringent penalty, which means they never take any stringent action against repeat offender. That also indicates most spam calls originate from Registered telemarketers, against which they don't take any action.
But I remember, 5 years back without TRAI DND, I used to complaint with Airtel customer care thru email, at that time penalties of disconnection of mobile/landline numbers were common. I received several confirmation messages of disconnection of repeat offenders, some of them even called for apology and requested for taking back the complaint.
But now Govt has intentionally scaled down the penalty levels, as these telemarketers provide a good revenue stream to the Telecom operators.
100% agree. I am now reporting all spam calls on dnd 3 app.
