Same thing here. They called, I ignored, they left a 4 sec vm but nothing was said on it. I get 2-3 calls from different unknown numbers DAILY! When is this nonsense with these companies going to stop?
Caller left a "silent" VM on 3 different occasions. Possible telemarketer/scammer, judging from other reports. I finally blocked the number because it was a nuissance.
We seem to be victim's without any resolve. When we block one number, they call using another. Yet these businesses hide behind obscurity. Their "do not call list" confirms your number as 'active', and is sold to other despicable entities to amass unlimited profitable gain, at our annoyance.
