Worried about scam

So I got too excited looking at the Nashville tickets and saw there were only four left so I hurriedly bought two. I was on vividseats and thought that it was the venue’s selling site (I literally never go to concerts or comedy shows) and then realized it was a resale site. There’s a 100% buyer guarantee that they will get you your tickets but I’m still super worried. It says the estimated email delivery date is March 14 (show is on the 15th). I paid $80 per ticket plus fees and I’m not as upset about the money as long as someone can tell me it’s a legit site😭 Also concerned seeing as the tickets are technically still on pre-sale until tomorrow morning so could someone have bought the tickets with the presale code and then resold through vivid seats? Thanks to anyone who knows anything about this.

TLDR; Bought two tix to so true nashville on vivid seats, worried it is fake and won’t get my tickets.
