We have gotten many calls from this "missouri" number on our home phone. Nearly everyday. They never leave a msg on the machine and when I've picked up, they hang up. I am a Wyndham member, if that's who it is calling, but why not leave a msg or say anything when I answer? Getting pretty annoyed with this.

I've gotten a lot of calls from this number.  Leaves no msg.  My Digitone Call Blocker blocks the call and logs it as a blocked call - so they can't annoy me once I placed the number on the Blocked List. I don't think I am a member of GMC Vacations or Wyndham Resorts, but I'll check on that issue.

Wyndham Rewards

Someone keeps calling from this number over and over.  If you answer, they hang up.  It says Missouri.

I called this number back and found out that it is GMC Vacations calling Wyndham Rewards members with a promotion offer.  It is not Wyndham themselves.  I asked to be taken off the call list and was told they would do so.  They are having problems with their system causing it to disconnect when someone answers.  Not me problem but they were cooperative.
