BSNL Kerala — Non activation of desired plan (199 roam free)

dear sir.
I recharged my mbl no [protected] for rs 199 from bsnl portal for rs 199 roam free plan (as shown by BSNL kerala portal) on 09 feb.
i waited 24 hrs for the activation of the service .
even after 02 days the service is not activated.
helpline no 1503 and mbl no [protected] are not responding.
in short m not able to contact with bsnl at all.
I even tried registering complaint online but in vain.
m facing lots of problem and financial loss on roaming.
please help me out.
thank you
