Complaint Review: Global Crossing - Startec Global Comm

I received the following USBI charges on my Verizon Bill dated 6/14/04:

May 10 2004 5:51PM to Solomon Is for 28 minutes, charges
from Global Crossing of $88.71 plus tax.

May 16,2004 6:42PM to Diego Garc for 25 minutes, charges
from Startec Global Comm of $31.54 plus tax.

Although I was on the Internet both days I have no knowledge of making a connection to web sites that would require me to pay toll charges to USBI via Verizon.

Calls to both carriers provided me with no help or relief

Should I withhold payment to Verizon pending an investigation by a third party of misuse of computer telephone lines by USBI.

I would appreciate your help on this problem.
