It's definitely a scam because I never owned a Harris Bank account.
Scam artist managed to illegally obtain mass lists of cell phone numbers and send a text out to hundreds of people in a phishing attempt to scare someone into calling them.
Then if you are dumb enough to call,  they try to hook you into wiring them a payment,  so do NOT believe these types of texts and do NOT respond to them.  Once you respond,  you help them verify that your cell number is good and they will pass your number to dozens of other scamsters.  Your phone will then NEVER stop ringing or getting text,  so just DELETE these type of messages and simply ignore them.  I get them roughly 2-3 times per year, so it doesn't bother me, but if you are getting them constantly, then it's probably a good time to consider changing your phone number.
