Called my cell phone, left no message. Called back using *67, got fast busy initially. Called again and got same message as shark12. Listened for 5 or 6 repeats of their "Lisa" message then just set the phone aside to let it repeat itself to tie up their lines, if even a small fraction of a percent. Not sure how long it went on.
I received a call from this number 50 minutes ago: Caller hung up after 2 rings. Oddly, a looping voicemail message on my iPhone stated that caller is from a "rewards" company, that I had earned a $100 gift card, and that I press "1" to redeem the $100 gift card or press "2" to be placed on its Do Not Call List, on which I am presently listed. To leave the voicemail loop, I must hit the voicemail's RETURN CALL button/bar on the top of my cellphone. Instead, I opted to shut my cellphone off but oddly, instead of shutting down, my phone automatically called the voicemail's number.
