I didn't receive a call from this number.  Instead, I researched it after finding it on a website selling diet drugs since their website did not give any information about the company's location.  The number is listed as Liposomexlabs, on their website www.liposomexlabs.com and their related website www.phentreminediet.com.  All I've found so far is their location of Tampa, FL (based on 813 area code.)
