I have make 3 chekes 4 amount of 8000$ & I don't have to bay what can I do??

I don't understand, do you want to cancel the checks? Call your bank, they will do this for you.

They have went to the bank and taken an refues on the chek

Is it because you don't have enough money in the bank?

Your language is very hard to understand, please bear with us.

Yes, was this checks someone wrote to you, or checks you wrote to someone else.

I can only guess english is not your main language so please take some time and spell out in a lot more detail as best you can what you are talking about.

Like I wrote three checks one to >>>>> and so on, why is there no money in the bank, did you know they were going to bounce when you wrote them?

If you received them who paid you, for what??
