Apta Leads Fraud, Cheat selling inaccurate and inappropriate contact list Austin Texas

We were approched to purchase attendees list from this company, we asked if it's a genuine list and they assured yes and also promised refund. Worked with two different people out of this "business." They solicited our company to purchase leads/ contacts from a recent conference. We paid $1250 for the leads. The list they provided did not contact accurate contact information. We have confirmed that the leads are indeed fake and not...representative of the people who actually attended the conference. Now, both employees will not respond to emails or phone calls. Their main telephone number is simply a recording of a Chinese woman speaking. We are not able to contact them for a refund at this current time.
