threats about an attorney

Not sure who he is. Claims I have a phone deposition to do today.

yes, also called me about a phone deposition???

I got the call today. It sounded very serious in the voice mail so I immediately called it back.
Is this a scam?? Should I be concerned??

I have also recieved calls from them claiming some sort of legal action and claiming I had a phone deposition. I am informed to contact "David Hamilton". I will not be calling back. First of all, the fact that I have recieved nothing by mail is a red flag. Second of all, recieving or making unsolicited or unrequested phone calls are not legally binding. Therefor, since I have neither requested or agreed to a phone conversation, I am not in violation of anything by refusing to take their calls or refusing to call them back. Finally, if they are taking legal action, it is my right to be notified in writing. Any legal action taken against me without this proper notification can easily be contested. My advice to anyone getting calls of these types is to know your rights!

Got a call about a deposition that i "missed". When i call back there is no name of a company just threats about summons and depositions....
