I am receiving huge SMS daily from BA-ValueBuy, TM-XYZ, TA-XYZ on my mobile no – 9323737316.

Please help to stop this permanently . My DND service is active but still I receive a lot of spam SMS from the above. I’ve logged a complaint to my service provider but still not happening. It’s really very very much disturbing to receive 15 – 20 sms daily while on the work when I’ve never subscribed to any stock market and not investing anything there.
