The main phone number at 3011 University Center Dr, Tampa, FL 33612, 813-971-1065, and the fax number, 813-975-0649 to this location is faux. The billing department called from this number and left a message requesting a return a call. When called you receive only a busy signal no matter what hour the number is called. The fax number is also bogus because if you send a fax it rejects the fax and hangs up. They also do not leave any other identifying information on their voice mail other than their first name. How is a person to return a call to answer a questions?
