Please help me to correct these sentences

[MAJSH]

Please find attached the copy of my telephone bill which I marked personal and business calls separately. I was not able to identify most of the calls that received as the bill shows only provider's center no / message center no instead of the calls received number which is very difficult for me to identify who was called me while I am on roaming. Therefore I clearly marked the unidentified numbers separately, and the rest I leave it for you to make finalize.
