“What I really want to avoid is paying money for the setup and finding out after a month or so that the service sucks and I’m locked into a 24 month plan that would cost a few hundred dollars to get out of.”
Can you not express exactly that to the rep?
On goodness after the install and cancellation if the service doesn’t pan out, the stock line seems to be “the installer makes sure it’s fine.” I did see one promotion (not sure which service) where they had 30 days after install for cancellation without penalty.
