Aussie bob is correct, I would urge against sending the vendor too many messages unless a reasonable length of time has passed. Vendors just like everyone get busy, stuff IRL crops up etc so they may have just gotten a bit behind. Given that you have finalized the order though you will be unable to seek assistance from SR support if there is an issue, for now though I'd just sit tight for a little bit longer and see how things pan out. Obviously if you do not receive your order and/or the vendor continues to ignore you them please report back here with an update.
