Is this Auli Skiing course providers legit?

Hi guys I've been trying to book a skiing package and Google searches frequently brings up this course provider - https://www.auliskiing.in/ There are a few red flags that immediately caught my eye. The name, the website condition were a few early ones. But I figured they aren't a large set up and more local so they might not be the best at presenting themselves. As I interacted with them over the last week or two, few other things stood out - their responses seem very infrequent, - the details are vague unless I pushed for them, The key point is their packages are quite expensive, so i was expecting some standard. . - Then they sent me the wrong amount on the form I had to fill, it was a 50% increase on the original amount for the same standard package. - when pointed out, they said just edit it to the original amount and send back. - 100% payment is required upfront. I would understand if it was a deposit but a full payment up front is a bit much considering I have no way of confirming anything.. - no real reviews around. They refer to their group as GHAH but couldn't find much online. Any one has encountered and worked directly with this skiing provider? Any thoughts on this would be greatly appreciated!
