I have a negative balance over $200 and I’ve never used my Apple Cash how!!

I got a notification saying that I was negative over $200 in my Apple Cash and I have never used it. I’ve never had it so I don’t know if the past it automatically made my account but I have never used it for anything so I don’t know how I’d be negative, and I found this out by a friend trying to send me a little bit of money and them not knowing I didn’t have Apple Pay and then I opened it and it was negative over $200 and like I said I’ve never used it. I’ve never hooked up no debit or credit card to my Apple Pay.
