Mega Bundle not available for purchase

Like the title says I cannot buy the mega bundle of the most recent expansion.
I could see the bundle in the in-game shop but now its missing.

I had all the bundles available in my shop, I decided to get the March of the Lich King Tavern Pass, Arthas Menethil Bundle first, after those purchases ware made all the other bundles ware still available in the shop. After that i bought diamond Lady Deathwhisper and normal Path of Arthas set with in game gold. This is when March of the Lich King Mega Bundle disapears from my shop. I can see the bundle in the battle.net app shop and when i try to make a purchase it tells me that i already own it when i certainly do not.

What i think is causing the problem is path of arthas set being part of the Mega Bundle, and me buying it with gold causing some weird bug where the game thinks i already own the bundle.

Opened some customer support tickets, been told they are aware of the issue and that it has been fixed when it wasnt. I kept opening the tickets and been getting links for bug report forums which always lead to 404 error page untill recently. Was even offered a refund just to be denied it in the next ticket.

I am trying to give you guys money and you are making it very hard.

Yeah I have this issue as well. I think it’s tied to buying the Path of Arthas with gold or something like that. I purchased the tavern pass with the same debit card earlier in the week. Bnet store/client shows me owning the Mega Bundle which I clearly don’t.
