The telephone number 844-646-0667 is being used by scammers. Scammers are sending potential victims fake and phishing PNC Bank text messages asking them to call the same telephone number. Therefore, I recommend that people take precautions if they are asked to call 844 646 0667, or receive a call or text from it.
I will update this alert as I get more information. If you have any information about 844-646-0667, please share in a comment below.
