Airtel — Unable to make calls 3102022

I have activated dnd service with airtel to avoid unwanted calls fro telemarketer and other phisers . Now airtel has blocked me from making calls saying that I have been making unwanted calls . I am a banker and I do make calls to my own contact list since that bast 8yrs . Yet on this day they chose to limit my calls to 20 call/day or sometimes even block my number without even making a single call as well . The service provider chose to do this without any logic or intimation. They icing to the cake is whenever I try to make a call I get a service prompt saying that I haven't paid my bills which is why my service for making any outgoing calls is blocked but in reality there is no payment due even for a single day . When I talk to the service people ( Today ot was Mamatha : supervisor)they nonchalantly answer that "for further info you can just check our website or send an email". I am right in between work where I need to make important calls and this is what I need to run after. Without proper intimation or adjudication I made to suffer for not a mistake of mine. Need an immediate resolution
