Dear Elizabeth Knowlin ..
800notes is not affiliated with your textor, we are not texting you either. 800notes is a forum for reporting who calls you and any information you may have about the call to share with other forum users. It is highly doubtful that the people texting you are reading here either.
You should report this to your phone service provider and also see if your phone has blocking capacities, if not, there are free apps for that online and you can google your phone model and brand and see if one will work for you.
