As subject said, please teach in details how to withdraw all the funds in my account balance if I were not a seller?
PS: The funds that I deposited was by my credit card at that time
Are you talking about your trading account?If yes so please contact with the broker you deposited the money to.
If you are talking about this forum account so read the following article: MQL5.community Payment System - Withdraw from Account
Because you told about "account balance" (and it is mostly related to the trading account with the broker).
If you deposited to your forum mql5 account mistakenly so you can write to the service desk with explanation (for example - why did you deposit to this forum account? and why to withrdaw?) asking them for withdraw (to allow you to withdraw).Because as far as I know - the service desk accepted such requests in past (with explanation of course).
