It is better to make another wallet if you don't want to pay for a 2FA service.
Simply create a new standard wallet and send all your funds into it.
To check, your new wallet should start with "1" rather than the multisig address "3".
No, the 0.002 that OP paid the first time is a batch payment for 20 transactions, that's how TrustedCoin works if you don't bulk prepay. So OP actually has 19 more txs he already paid for.
And also OP doesn't have to create a new standard wallet. As is explained in the message that shows up when you choose the 2FA service by TrustedCoin, your coins aren't locked in the service. If OP doesn't want to use it anymore, simply restore wallet using the seed phrase, without the service.
