Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives
you the wrong answer.
• You don’t have a purchase order number
and the tech refuses to help you.
• It’s 9 p.m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communi cations magazine, 90%
of network managers surveyed say that getting the technical support
they need is extremely important when choosing a vendor. But even
though network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support contract, the
technical support and service they receive falls far short of their
expectations—and certainly isn’t worth what they paid.
