Im waiting for a reply for 28 hours now, and as its related to weekly bundle it might runoff

Post to their twitter "support ninjas", they'll fix it for you super quick. It's kinda cheating, but it works.

Just contacted them ;) Few of my links from Humble Square Enix Bundle were not working - for 1st reply I waited around 1-1.5 day, asked me for detailed list of games, as they couldn't verify them just by links - then after list was send after 5 hours all games were revoked and reset. I must admit it was quite a pleasant surprise and nice experience comparing it for example to Steam Support (my payment wasn't processed once and I had to wait over 2 months to get a game I paid for).

i didn't even receive my bundle and its one and half day since i sent the ticket :( and still no response

Great. Working. Gods.
Somebody had used a lot of my unused gifts. Contacted them, provided some transation information and now I have my unused games back.

Slow, yes. But kind and helpful.

I had a bad experience recently. I was trying to buy second (sic) copy of bundle as a gift and triggered "too many purchases" limit. I asked support for help thinking it was an error and they told me to use different payment method every time. Yeah, because I want to give them all my credit cards details (normally using paypal), and this certainly don't fall under "suspect behavior" category. They also refused to tell what are exact limits to purchases, a thing that should be included in FAQ.
I was buying two bundles to gift and play with my sister, one copy is pretty useless to me, so I'll never buy HB with that intention again. Good thing I didn't buy tier 3.
Sadly to say, the bundle pioneer is't doing very well recently :/

Humble has good support but horribly slow. Possibly burdened by so many requests.

I once bought a game from the Humble Store by mistake (I thought it had a Linux version, but it didn't.) It took them a week or so to get back to me, but they did a refund, even though it was my mistake, not their fault. As if that wasn't enough, they actually didn't revoke the game. They just gave me my money back and they left me the game anyway...

These guys made me feel bad, actually.

So yea, I'd say their support is top-notch.

supppraaa fast, got answered in like an hour
