Hp Gas Online Booking — Didn't receive activation link after registration

Address:

Thane, Maharashtra

I haven't received HP Gas Online Booking activation link on my gmail id. dattatray.[protected]@gmail.com. Did registration on 03 Aug 2015. If we try to re-register.. it says already registered but can't login. Because it is not activated. And there is no alternate way of login or asking to resend activation link. Regards, Dattatray Mandlik
