I found just now that my telecom operator - Airtel - randomly subscribed me for OTT services and charged me for it. But upon calling them and contesting, they just asked if I want to unsubscribe and then reverted the charges. No threats, pleading, or back-and-forth involved from either side. Mildly surreal.

I wonder that's a new corporate strategy - charge randomly till someone goes through the pain of IVR and spends 15 mins with support. Must generate quite an upside for them if it is indeed a strategy.
