Kindly correct the following sentence (It's very urgent)

Please note that we reported to Mr. X on / regarding the above defects,

But Mr. X saying that It's a x piece, we have to install it, no other option

It's more natural to say:

"Please note that we reported the above defects to Mr. X, but he said that it's a x piece, so we have no other option but to install it."
