I managed to contact samsung. I gave up on phone as I was on hold for over an hour (!) but managed to contact them via their chat system (after waiting for 45mins)
Here is tha chat:
shawn : I got the registration confirmation for my Galaxy S8 promotion.
Sireesha M: Hello, Shawn.
shawn : After I registered it said upon approval I'd get a link to purchase the 99 dollar immersive bundle in the email. I chose that option during registration, but my approvval email does not have a link to get the 99 dollar bundle
Sireesha M: I will be right with you.
Sireesha M: Please give me a few minutes to review the information you have shared.
Sireesha M: I see that you need the information regarding the 99$ bundle registration.
shawn : yes. i got the email saying my registration was approved. and said my free Gear VR was on the way. thats great, but I do not have the option to purchase the 99 dollar bundle that has wireless headphones and memory card. I chose that option during registration, and it said id get link in approval email. my approval email did NOT have a link to purcahse it
Sireesha M: Not to worry, Shawn. you will receive the email with the payment link with in 24 - 48 hours from the registration.
Sireesha M: As your purchase is confirmed you will be receiving the email with the payment link in a shorter time.
shawn : So the email with a payment link is a seperate email then saying my registration is approved? im just a little confused as other people have said that the purchase link was in the same email as their approval
Sireesha M: Yes, you will receive a separate email with the payment link in it.
shawn : Ok. I submitted my regustration yesterday. got the approval email today for my free gear VR, and another email will come in a day or so to purchase the 99 dollar bundle?
Sireesha M: Not to worry about the 99$ bundle.
Sireesha M: Yes, you are exactly correct.
shawn : OK. I was looking forward to grabbing the 99 dollar bundle, I know it was limited quantity. I did not want to miss it
Sireesha M: As you have already registered for the 99$ bundle, you will shortly receive the payment link too.
shawn : Are you able to see in the system that the 99 dollar bundle was chosen during registration? I know some people had issues with the website early in the day yesterday. I just don't want to miss it due to a system glitch
Sireesha M: We at Live chat, don't have the option to check for the status as per the security issues.
shawn : Ok. But I will get a seperate email with purchase link then?
Sireesha M: Yes, Shawn. You will receive the email with the payment link.
shawn : OK. Thats all I needed to know.
Well...not sure how much faith I place in this...but she seemed certain that I will get ANOTHER email with purchase link. This is not consistant with what some people have gotten, but it seems like this entire promo process hasn't been consistant. I'll update if I get another email.
