Got a missed call from this number +20151001 at 6:34 pm on 2/5/20015. Weirder than it not having an expected amount of digits, the call didn't even show up in my missed calls log until I rebooted my phone several hours later... Hoping it's nothing to be concerned about, my phone has been weird about missed calls and texts before. Though, my phone keeps connecting and disconnecting to my wifi and that's new...
I answered by mistake and it was a message not a live person telling me my debit card had been locked and if I want to reactivate, I need to press 1. I pressed 1 to see what was next and it was still a message but this time asking me to speak or key in my card number. I hung up.
