Nextra Teleservices — Refund of security money

Address:

C-53, DDA LIG Flats Pocket-2 Sector-7

My broadband connection is closed which was registered with no [protected] because of poor service and poor local support. However, after a gap of 3.5 month my security money has not been refunded.
Kindly do the needful.

Yours
