Contacted me wanting to buy account. and just kept putting off payment.

Hello, This buyer contacted me via skype wanting to purchase my league of legends account.
He offered to buy me a prepaid giftcard to pay for the account for $75. He ended up not doing this.
He then said he would send via paypal and ended not doing this either.
After I contacted him again he said he would purchase a card again.

I told him how i felt about him saying he would do something and then never done it.
He goes and throws a fit about it and starts saying im rude and stuff.

I turned down 5 other potential customers holding the account for this guy. completely wasted my time.

Try to not deal with this customer.
