Recognize 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
Communications magazine, 90%
of network managers surveyed
say that getting the tech support
they need is extremely important
when choosing a vendor. But
even though network managers
pay 10 to 20% of their overall
purchase price for a basic service
and support contract, what they
get falls short of expectations—
and isn’t worth what they paid.
At Black Box, we guarantee
the best value and support. You
can even consult our experts
before you buy if you need help
selecting the right component for
your application.
Why Buy From Black Box? Exceptional
Value. Exceptional Tech Support. Period.
