Bharat Sanchar Nigam [BSNL] — validity got over before the expected date

I recharged my bsnl sim for rs. 349 on[protected] and the validity showm in the website was 54 days but on[protected], i received a text message that the validity of my recharge is over and i have to recharge again. My phone number is [protected]. I either need a refund for the recharge or need to get validity of my next recharge extended for as many days as i lost in the previous recharge.
