I'll call it scammers because they texted my cellphone and put an emoji blowing me kisses with heart's! I didn't even click on the message because it could have been a Virus or Something of that nature?

Always a recorded message to call. I've been reporting to DoNotCall.gov for months with no relief. I have called and demanded they take our business off their list to no avail. Beyond frustrating.
