Un solicited SMS spams

I keep getting unsolicited investmet tips from BZ-SHREESTK by way of SMSs. I am utterly untinterested in this.

Besides this source, other sources are also sendign share investment tips. This is inconveniences me, espcially while driving. This is keeping me from attending urgent SMSs immediatly.

Kindly block SMSs from this source or any other source that markets share tips.
