They called once, I didn't pick up. Tried to call back but it does a tone and tells me that all representatives are busy and cannot answer my call, and to try to call again later. Pretty sure it's a scam.
This isn't the first time a number like this has tried to call me. Usually, it's people giving false information, and giving a random number, or they found your number on a different kind of source, a way they probably shouldn't get your number. But they do anyway.
If you want to block the number, you can usually set their numbers to call reject on your phone, depending on your phone company. Or just simply call the phone company and tell them about the problem. Good luck to all others! Stay safe online and on mobile! :)
