I have no complex tax issues. I owe no taxes and I pay my taxes but I got a call from Kyle Miller (from Omni) who just said for me to call him back. No reference. Two chances of that happening. Slim ... and None. Caller blocked. End of story.
Received a message from Jeff Gray with Omni, regarding federal filing with our business. Looked up the number and I found this site. So glad to be able to look up these scams, before wasting my time arguing with them.
I got a call from this number from a guy who didn't tell me his name, and asked me for the CEO of our company. I told him this was my private phone, and sent him on to our operator for them to obfuscate.
