Hacker ESC X-70 Pro Problem

I get very very limited throttle response, at full throttle the motor spins as if I had 5-10% throttle stick movement.

I believe the problem is with the ESC after reading in the Manual what a "Normal Start Up" should sound like
"... you will hear a number of tones which indicates the number of cells the ESC detected and two tones for brake OFF."

when connecting the ESC to the battery I hear 2 tones and thats all, I tried setting up in the programing to 4S as I am using but nothing changes.

any ideas?
could it be a defective ESC?

The motor is Hacker A30-10L with 4S 3300mha

any help will be greatly appreciated!
