Tried that, and couldn't get through, tried something else, and still couldn't. Tried everything, and still unsuccessful, so what do you get? Frustration.
Frustration, the transitory state of mind that occurs when reason fails, and anger takes over. Frustration itself becomes an extension of that failure, so usually produces failure.
At the sign of frustration, it is better to rest, withdraw, or retreat, and then to tactically invite recreation, advice, or new thinking.
