Airtel — non functioning outgoing calls on [protected]

Address:

26/C Surath Chandra Banerjee Lane, Hooghly, West Bengal, 712235

Sir
This is to inform you that i am not able to call anybody from the above said number since 26th nov 2019 after recharging on 15th nov 2019 by rs.399 with 84 days unlimited call facility.
I have contacted nearby airtel retailer as well as airtel service centre, konnagar, hooghly, wb but in vain. Presently i am not getting any airtel service for outgoing calls. So please do something about it.
Thanking you

Yours faithfully
Subir kumar das
