don't download this app called " Delivery" it is a fraud .

I am a teenager and I wanted to delivered some personal item to my best friend so just today I downloaded an app known as delivery app and as per the process I put the pickup and drop address to be delivered in the app and many other information. And then I was asked to pay online so I just pay the amount to that app .But in the app it was like we didn't received the payment while I had already paid it and my money too had been transferred from my account , but the fraud app wouldn't show.I also tried the helpline no" [PHONE]" but it didn't work 😭😭.And just like that I was being scam☠️☠️..
