What should i do.

This instagram account is organising this FURFEST, where one can bring or meet and play with pets. And i did the formalities that were asked, filling the form, paying the fee, to buy the ticket. And the website said that I'll receive a confirmation mail (within 48 hours) with some sort of code or something to enter the event. But it's been over a week and I've tried different emails, checked spam folder and Bin, but got no response. There were 3 contacts mentioned for help or quarry, so i contacted all the 3. And they simply said that I'll recieve the email in a little while, it's a technical glitch. But I didn't recieve, and i tried messaging them back they have stopped replying. What should i do next? The event is on Saturday.
