I completely agree septictank.
I always make sure that my customers aren't left in the dark.
Something would of left that door open for you in your mind that led you to believe otherwise - that the GM was going to respond to that info. This is not a dig at you. You've done nothing wrong, and I'm going to try shed some light on the issue you just raised.
Basically you weren't given the right service. This is usually driven by fear.
What I'm trying to say is, you weren't told that you wouldn't/couldn't/shouldn't be responded to because the GM was too afraid to say it. Or had a preconceived idea that you already knew this. Unfortunately most businesses that don't stand behind their reputation will put this back on the customer saying it's your fault. This is not good customer service, and certainly isn't good business practice (It actually compounds the issue further). Aside from the fact that it places blame on the customer, it's a recipe for more issues later on down the track. (As I said they certainly didn't paint a picture of what to expect next).
I always ensure that if I'm going out of my way at work to handle something, I make sure I'm going to handle it, and I cover my bases. IE: If I knew I couldn't/wouldn't/shouldn't respond to a PM but still wanted you to PM me I'd say something like:
"This is something I don't normally do, but are you able to forward that info on to me in a PM? I probably won't respond because it's not something we do very often, and as I'm sure you can appreciate, I'm very busy at the best of times, however, if you could send that info across, we could at least look in to the matter." or words to those effect.
That way, you get the idea that if you want to follow up on the matter, you'd have to do it yourself via the appropriate means, and it does not create issues later on down the line.
Providing good customer service means tackling things pro-actively as opposed to re-actively (most businesses fail here). This includes but is not limited to any potential issues one can see. So it's not as easy as everyone makes it out to be. It's not just about being polite. You need great interpersonal and communication skills, great mental fortitude, discipline, and integrity.
