Tell your friend to give you the tx id then, simple as that.
No, you didn't, you just said that a friend of yours made the transaction.
Maybe your friend never send those bitcoins, if you don't know how bitcoin works how did you get bitcoins in the first place?
I told you, although I tend to believe 99% of the services that offer paypal/vvc and other related stuff are scams your story looks fishy also.
Show us proof you or your friend sent 350$ worth of bitcoins, not a random tx from the chain, and I'll personally tag that account the next moment.
