Matrix Business Services — payment related issues

I worked with matrix since last 6 months, 1 june month bill the paid, but july august september and october month billing totally i haven't got a single payment.
I have each and every documents.
They cheat with me, when i call the kolkata branch they always informed that payment will be done by this week, but it's still 4 months not credited.
Before a few days ago i informed about the matter to the hr of the chennai branch, he corporated just a single week, but now i called him, mailed them, no response.
Totally 70, 000 billing of 4 months not cleared.

It's over i will raise a police complaint about this matter.
And one more request to all the people never deal with matrix, all they are cheater
