Unwanted and unsolicited spam sms received

They have obtained and used my personal details without my consent to contact me without my consent. I consider this spam. IBecause of this have added them to my personal blacklist of businesses I will not do business with or recommend to other people I know. I require them to permanetly delete all my personal information from their systems and not to contact me again. If I could give a rating o0f no starts I would.
