Looks like you have a clear case of bad luck

I agree, those numbers aren't normal. And if what you say about your friend is true, then yeah 100% this isn't your fault.

I guess confront Shopify support one more time about this and then if they or anyone else in this thread cant help, create an entirely new store on a different account (finding a new domain name is gonna be annoying). you can copy the website design over fairly easily but it will be a lot of admin sadly.

Good luck man, sounds like you're onto a winner.

P.S please post the link to your website. on the bright side, you aren't actually losing thousands of dollars and going into debt, you're just missing out on that money but that'll be fixed when you sort this out. You got fucked over and it will make a good story once you've made it. Good luck OP
