I dont have pending transactions on the account , and the fees cannot be the problem because including the fees it will be 6600$ - 6800$ , and my balance is 8700$ , so what is the problem with the rest ?
It can be a bug from blockchain wallet. Try to export your seed phrase from blockchain wallet and import it into another wallet like Electrum. If you really have that amount of bitcoin in your wallet, you should be able to spend it using other wallet.
i am not able to make a connection between the blockchain wallet and Electrum , i used my recovery phrase , and they didnt detect my wallet , no balance shown on Electrum
