Got the same call, it was strange and was about the same time frame as others. It is very important to return this call. The person said that they tried to serve me but they did not have any documents with my signature on it, and they had a file in California, and they left out of state numbers. Just another scam...

This is a land line and it is registered to a Michelle Dacz (or some idiot) from Lake Helen Florida. Its a land line in Florida, and its a company claiming to sell medical technology and medical supplies. There is no way they have my real home number, because I am in Canada.What will happen, if anyone knows how to take care of thier scam, please pass it on. If I ever call again, I will call them back using a Voip line.
