Bharat Sanchar Nigam [BSNL] — scam call from bsnl or hungama

Address:

Thane, Maharashtra, 401504

I got a call on my bsnl landline from hungama (I know this was surely from hungama as it was 5.15 and bsnl offices are not working so late and also i tried to reach to kalyan bsnl after that. But my call was not received at 5.15) hungama person said that whether you are facing any problem with your bsnl net as i was having it from 1 month i said yes then he told me that you will have to send an sms for that from your registered mobile bvas to 56677
But i thought something fishy is going on as i never complained within this week.
So i searched the net and saw many people receiving this call so i hanged up the phone and try searching but my luck was with me and i saw message on my bsnl sim that if you want to activa te hungama services send bvas to 56677 so i angrily asked him and i hanged up.
