Feeders pulling fabric out from the back to front?

Hi
I have got a little problem with My sewing machine .

It's been some time already after guarantee expired.

Not so long ago, during bottom hole sewing ,after using [T] style on machine , my machine stayed on backward style of sewing, and keep pulling material in other side that its should.
Unfortunately I could not reverse that action.

I have been trying change styles to others [A>B>C>D>.....] and nothing working right way all of them going in to back instead of to front..
The "the pulling teeth don't wont to come back to position before.
Please Help Me!!!
