Indiegala : What should I do ?

Never had this kind of problem, but their support is sometimes slow. And they don't work on weekends, if you sent your ticket on Friday that's why it's taking so long.

they slow because he send 2 emails
"What should I do in this case ?" send a other email facepalm

did the money was taken from you? maybe payment failed? did you check your email for indiegala purchase email? did you check spam?

I had an issue with a key saying that it was "not available". I emailed them once and they never got back to me. It was a giveaway game so I didn't bother with it for a while, but then I emailed them a few months later saying it still had the same issue and they got back to me right away and fixed it. I honestly think you just have to get lucky with the response... I would think they'd be a little more attentive since this was games you actually bought, though.

Be patient, when I had a problem (they didn't like me using a VPN), it took indiegala support about a week to get it fixed.

Did you buy more than one bundle of the same? Because in this case unless you check the "Yes, this is a gift" box, the payment goes through and the bundle gets lost. It must be recovered by their support by converting them to gift copies.
Anyway, just wait. It may take a week for them to respond; they got quite popular, so a lot of users to work with. At least it is still not as bad as Steam support. (Plus IG support does solve problems… eventually. :))
