BSNL
Irrelevant SMS waking up at midnight

I am aged 71 and have to take sleeping tablets as a result of minor stroke. I am holding BSNL prepaid mobile connection 9433153462. BSNL indulges in irrelevant SMSs at round the clock saying some girl is waiting to talk to me in the mid night. With a SMS to START DND, I could stop all unwnted callers with Airtel and Vodfone but failed to cover BSNL who continues to send the SMS stating some TRAI reference. Has TRAI given authority to call centres with starting no.5 viz. 59595, 57272, 54000 etc. to disturb Senior Citizen's health? I want to stop all incoming SMSs (except Greetings being delivered in day time.) How to stop these? Please advise me.
