They Need Auto Software

Just recently bought a new lawn mower, though it hasn't worked properly since we got it, so we've taken it back to were we bought it in the hopes they can get it repaired or maybe even replace it. There's a problem, the store doesn't seem to know what they are doing and they don't seem to know how to keep track of the progress, it's been a couple weeks already, seems like they need some auto repair shop software or something to keep track of everything.
