thanks a lot to everyone.

@Hitesh Yadav and khandelwal.shweta,
Please don’t quote the whole original post. There is no point of doing that, and it makes finding your reply difficult. Unless indicated otherwise, it is assumed that you are replying to the original post.
This should be one of the correct translations:
I have reminded you many times about my ‘FOC material’ and every time you said we would get it the next day, but I haven’t got it even until now. As a result, there is a pendency on you for the month of may. Only when you clear this pendency, will you get your cheque. In the meantime, please don’t cancel any of our next orders for this reason of not getting your cheque.
