Well... I'll agree I could have called. I didn't think of it that way. Looking back should I? Probably. Lesson learned. Still, I don't think that what I was asking for, in light of the reasons I was asking for wad extraordinary or unfair.
I ended up being able to change it for a small fee. That worked out. But I had to email a bunch of people until one responded, correctly, it didn't make sense and would try to help. They did.
To the argument of "it's ticket conditions etc" I can only say I agree. And if I was calling to change a date or whatever not that would make sense. My point, which thankfully resonated with someone was that I was not asking for a change because I wanted it but because there was a technical glitch and no proper info on how to act in such case. I run a business and making my clients accountable / responsible for issues arising from a fault on my end sounds... Not too customer centric at best ?
Anyways happy to report it's fixed and looking forward to enjoying their product.
