Claims to be from the office of Dr. Luis Casaubon from the Texas Diabetes and Endocrinology in Austin. They stated that I have an appointment with them, but I've never been their patient and I've never have contacted them. When I asked about how they got my information, the call dropped.
this caller called repeatedly, when the call was answered, there was no response, just silence. I took a chance and called them back, got a live person, and demanded identification, and the reason for the calls. He was looking for some stranger with no relation to my number. I asked to be removed from their call list.
