I got a message on my answering machine from this phone number. A woman claimed to be Sharon Escobar with Frost Bank saying that she needs my wife's social security number and driver's license number to complete an application. I called back and left a message before searching the number online, fearing identity theft. She called back and said she was trying to reach someone with a name nearly identical to mine who does have an account.  Neither she nor this phone number are associated with Frost Bank. Beware.
