I am receiving huge SMS daily from BA-ValueBuy, TM-XYZ, TA-XYZ on my mobile no - +91 9323737316.

(xyz after TM- stands for various name eg. FISCAL)

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