Keep your marketing to yourselves

I get at least 2 SMS's from Harmony Connect every single day. I don't know how they got my details, but this is not cool. There is no opt out option, and no matter how many numbers I block, they keep coming. Can this invasive non-stop marketing just back off. I wouldn't go near your product in a million years, and now would advise anyone I speak to, to stay away as well.
