Got the same exact text message on my personal cell phone also during past few weeks have got the exact ame message on my work (company) cell phone. Just ignored it because I do not and never ever had a Suntrust Account of any type. I'm pretty sure the scammer is doing mass texting looking for that one big sucker. Best advice.... even though it's a pain in the butt, just ignor it.
got a text from 917-376-2196 with a suntrust FDHL alert. said to call 718-715-1670, same as a lot of the above posters. used to have suntrust so was mildly curious... glad to have confirmation that it's fake.
