I am using blockchain.info as of my hot wallet for a long time.

So far I haven't faced any serious problem except logging difficulty (2fa email) only once.
And when I contacted support, I received almost instant reply with the solution.

Blockchain.info is a very busy site, so sometimes it may show some error and I think its very rare.

Well, what I told you is just my experience with them, but I am not tech guy who can solve this.

Please move your thread to Web Wallets
I hope you will find someone who can show you a way. Keep trying to contact them.
