This is a classic example of why it's almost always better to own your
own box and colocate it, especially if you have paying customers.  Yes,
it costs more, but having full control of the system is worth the added
rent.  And for a 1U chassis it's actually pretty cheap to colo at many
facilities.  The problem is finding one within sane driving distance
with low prices.

Your problem here is lack of a TOS agreement.  If you're providing a
paid service you should already have one.  In that TOS you spell out
what is/not allowed or supported by your service, such as 4GB attachments.
