Also hung up as soon as I answered identifying our company. Probably data mining, to sell third parties "quality leads" of company names along with the names of people who will answer their phone...
Also worth noting: NEVER follow instructions to press any keys on your phone; doing so may remotely give them authorization to place long distance ( and sometimes overseas ) calls on your phone account--making YOU pay for them!!
Your wisest move is to NEVER answer or call back these crooks; let your voicemail service handle their calls.
This is an example of this number being used as a "data miner", where calls from this number call thousands of numbers automatically 24/7, "marking" any that get someone to pick up and answer. This is how scam tribes create "hot list" sheets of potential victims, either for their use or for sale.
Hot sheets sold by scam tribes can command price tags up to $150,000--and likely beyond that.
Scam telemarketing is huge business--and all these calls are sourced from OUTSIDE the U.S., some from countries hostile towards the U.S. and allies!!
Your wisest move: NEVER answer or call back these crooks; let your voicemail service handle them.
