Why do people keep asking us to fix stuff that isn't ours?

From an email we received today:

>Hi, we bought one of your systems a while back, but it won't correctly interface with our current system. So I removed a few solenoids and added some relays and now the relays I added are sticking, please advise.

One, you modded the system. Warranty voided, officially not our problem anymore.

Two, we have a version that would do exactly what you're trying to do, but you specifically asked for the one we gave you.

Three, from your description and picture, you used a shit relay to replace the solenoid you removed. If it occurs to you to completely modify a control system, *why wouldn't it occur to you to try and swap the relay out?*

Tl;dr: I have no idea how you actually have this set up, why do you think I can help you?
