I bought something as a gift for my nephew for the Black Friday event but till the event almost ends, there is nothing yet. While I do understand the company could be busy at the moment, but are you also making more money too at the same time?

I was submitting support but it seems like they are using a third party support company and it just delays even more, no reply, not even an auto email saying that "we have received your requests".

Also, when I tried to download on Android, I just can't use my Microsoft account.

As far as I know there is no third party company for support or purchases for those directly provided by SP. The only third party company used is those for the tv ads, surveys and tasks. Only for those will you need to contact the third party to resolve issues. As far as your ticket to them regarding your purchase, sadly it is a small staff that handles the tickets for all features of the game so that could take time. And that does not take into account that this is a holiday week. All I can suggest to you is to try to submit a ticket again. Unfortunately for event issues you will most likely receive an answer after the event is finished, hopefully they will credit you accordingly.

@nynaevelan I have submitted the tickets. I just started 2 days ago, trying to surprise my nephew then giving him.
At this point, I just want refunds and out of the thing and go buy him some other things with that money.
