The Payment method you both are using here is prohibitet by the Forum Rules.
A. General rules
- Accounts that have been previously banned for macro use are not eligible for character sales.
- Lottery style sales are not permitted. Auctions and buyouts are the appropriate method for selling a character.
3. The character being sold must receive the ISK for the purchase and only ISK. Characters may not be sold in exchange for items. - The selling of accounts is prohibited; characters may only be sold individually.
- Bumping is allowed only by the character who started the thread once per 24 hour period. Friendly or multiple bumps per day are not permitted.
and :
D. Purchasing and sales
1. Down-payment plans are not supported by CCP Customer Support. As a seller, you are agreeing to a certain amount of ISK only, which is to be paid in one payment. Once again, any forms of scams regarding character sales are strictly prohibited.
2. Agreements on the forums or in game, or winning an auction does not guarantee a character will be transferred to you. The seller may choose to renege on a deal at any time, prior to the transaction being completed.
3. Whenever a character is transferred before the seller has moved the ISK received from the sale to another one of their characters, the Customer Support team will return that ISK to the rightful owner. The buyer cannot expect to receive both the character and the ISK that they paid to purchase it.
4. The ISK that a buyer sends when attempting to purchase a character is considered to belong to him until such a time as the character being purchased has been delivered to the account of his choosing. If the character sale is not completed, the ISK must be returned in full to the potential buyer.
5. Customer Support will not remove bounties placed on characters either as part of a sale, or after they’ve been transferred to a new owner.
6. The owner of the character being sold is responsible for paying CCP the character transfer fee.
So , for the Seller :
Transfer the allready Recieved Plex back to the buyer!
You can hold this Thread “on hold” until Buyer has the Ammount of ISK ready,
I expect a verification on both of you that the already paid plex has been transferred back within the next 24 hours.
If this has not happened by then, I will forward the case to support who will then look at both accounts and take further steps if necessary.
