Telephone number

Does anyone have a phone number for a supervisor in the US?  I keep getting the run around for a problem than was created by a rep from the online chat.  I now cannot log into my computer.  The number that I have 1-800-745-6034 is giving me the run around.  They were to call me by 10:10.  When I called them back, I was told that someone would get back to me today - as soon as possible.
