Have no clue. Left a message, probably automated since the first part is cut off on the message. Message did not say who it was, just days and hours they were open. I called back, was told the wait was about 1 minute 10 seconds. Then after about 45 seconds was told I was next. Then after hearing that several more times and 3-4 minutes later, I hung up. I have this number blocked with an app I paid for, so my phone will hang up and they can't leave a message, but the app (Extreme Call Blocker) is Not working. Mr Number didn't work on this number either, which is why I bought the other app. I think I'll just get rid of all phones, period. I'm sick of this garbage every day! Everyone is using phones and technology to be a thief and a criminal. Scams, telemarket creeps, insurance, auto warranty, surveys, debt collector criminals, win a cruise (bs), police charity (bs), vet charity, prize scam, home security, acting opportunities, credit help scam!!! Every day because I have a damned phone number, because I have a car, a credit card, a Kindle and Amazon account to get books, social media, email, etc!! And the do not call list is a joke!! People are horrible and are greedy criminals waiting to pounce on you!! Just Block this this number if you can!!!! Or answer and Tell them you've got room in your soundproof dungeon for them!! Good Luck!!
Another trick for blocking numbers is to put the pest in your contacts list and give them the ring tone "no ring" or "silence". Or you can identify the few people who are allowed to call you, give them ring tones, then set your default ring tone to "no ring" or "silence".
The Do Not Call List law does exactly what it was intended to do. Legitimate telemarketers - the photography studios and time share sales pests we used to get all the time - follow the law and have stopped calling. The law does not apply to charities or politicians. For a scammer its one more law to break.
Think long and hard before you get rid of your phone. At the very least you need to get VIOP (Voice Over Internet Protocol) service. Everyone needs the ability to call 911 in case of an emergency.
