BSNL — Rs 574/- recharge not working

Address:

West Bengal

I have recharged my BSNL number [protected] with Rs.574/- since 30/01/2013 and got the activation message immediately but still it is not working. It has already been 4 days. when calling customer care they are avoiding to solve it replying "we can't find the problem or server is down or It may take 4 weeks to solve etc." this BSNL to BSNL free (Rs 574/-) offer is real or just a freak trick to get money from customers. I want to file a case against BSNL if immediate solution was not done. kindly guide me.
