This is the question support is asked more than any other, and in almost every case nothing has gone wrong.
**The rewards in a VIP subscription are added one month after the purchase - after your second successful subscription payment.** The advertisements stop straight away, which is why it looks as though the rest has failed.
For example: subscribe on 6 December and the gifts are added to your account on 7 January, when the second payment goes through.
So if you subscribed less than a month ago, the answer is to wait for the second payment. Nothing is lost and nothing needs reporting.
If your second payment has already been taken and the rewards are still not there, that is worth writing to support about - and send your Player ID and your purchase receipt with it, or the account cannot be checked.
