@by-bel Please don’t bash and question the intelligence of others because you’re not getting what you want when you want it.
As far as I’ve been able to read up on the issue of FB connection (information that I’m sure you could also find), there is a known problem with connecting accounts to FB and we just have to patiently wait for it to be solved.
I’m sorry that support has not gotten back to you yet, I understand that that is frustrating, but rudeness won’t solve it. I suggest you either wait for the problem to be solved, or try contacting support again.
I don’t think anyone here can do anything for you, but I do hope you get your issues solved...

This is an issue that was caused by YOU adding your age in either your facebook account or you selecting an age that is UNDER the legal adult age of your country when the age confirmation button popped up. If you are indeed under the adult age of your country then there is NOTHING that SP or anyone can do because this is a rule of FACEBOOK. With that said, if however you have incorrectly added your age then you can try some steps but there is no guarantee that they will work. You can try to uninstall the game, go to facebook and clear the DC game from your settings and restart your device. Then you can reinstall the game and after the tutorial connect it to facebook. Do these steps ONLY if you have already successfully connected your game to facebook which saves it to their servers.

FYI I hope that you were a little more polite when discussing the issue with support, rudeness will not help get you assistance any quicker or at all. As I stated earlier you must be of a legal adult age to have purchasing enabled and if you are not an adult this is not an option for you. Also, you can try to check the settings of the Windows store to see if in app purchasing has been disabled. I do not know if this is an option in Windows but Google has one so I am assuming it is a possibility in Windows. While you are at it, check your Facebook settings to see if it has an option that disables in app purchasing.

@by-bel Ok. Sometimes solutions can be easy. You should not ask them to change your age. That is not possible. But I know that it is possible to send you a new age request in game. So you should ask for that and put your age then. I hope this will work and it was the issue. Btw. mods in this forum are players like you. Good luck.

@by-bel said in It's an unconventional situation. Buying game currency is disabled.:

I've been texting for a week and I'm getting really stupid answers. I get the impression that I am being ignored or do not know how to solve my problem.

It's like support in the Amazon - if you get on a non-American, you can't solve something, and if you get on an American specialist, everything is solved competently and quickly.

That's why I wanted to ask the community how I could write to the main office, where there are competent staff who can help.

I guess I'm not lucky and there are not experienced specialists who can't turn their brains on and give the right decision.

Lol sorry I disagree with you, I am an avid Amazon prime shopper so I deal with CS often, I have NEVER had to take it to a higher level, their CS is one of the best I've dealt with. One wonders if it is your approach and how you explain the issue and speak to them. Based on your tone from this topic, you do not make it easy to help you. And forgive me but that non-American statement comes off as racist......and I'm American.
