Somebody with a foreign accent wanting to sell me a vehicle warranty. I asked (very nicely) to be put on their no-call list and he nicely said he would. Maybe it'll happen.
Caller identified herself as Amy Stewart from Vehicle Processing Service and was calling about one of our cars. I told her I wasn't interested in anything she was selling and to please remove my phone number from her call list. She promptly hung up.
Got a call from this number and no one spoke and the call disconnected. I called the number back and got a recording indicating that my number would be removed by pressing 2. I pressed 2 and the recording started over again. I guarantee this did not remove my number.
