I am unable not create a new Apple ID with an error

No VPN has been installed now as it’s a new installation of MacOS.

I’m in Pakistan and creating the account of the same region.

The email address I’m using has never been used before to create an Apple ID.

Your request could not be completed at this time. Your account cannot be created at this time. Kindly also see the attached image below.

Basically I’ve an invite to a family sharing account and I cannot create an account.

What I’ve already tried:

Different browsers

Differently machines

Different mobile both iOS and Android

VPN

Incognito

Creating account through MacOS

nothing works at all.

That’s the thing I’ve waited a couple of days and it is still not working. I’ve tried contacting Apple but all I could find a service number which I can’t dial from my local carrier. Kindly suggest an alternative. Thank you so much for your assistance so far.

I found a way to get in a chat with Apple support through Messages and even after they tried several possibilities with me no luck yet, an escalation ticket has now been raised by the agent and I’ve to wait another 24hrs to see what can they do now.

I’ve tried all of the ways suggested in their support guide already.

I don’t think there is a support link available for my region, kindly see screenshot below.

Yes, I’ve tried that and it eventually goes to only a “call us” option, kindly see screenshot below.
