Loop to Delete Entire.Rows if conditions are met

Hi

I am looking for a way to delete Entire.Rows in excel if certain conditions are met. I have tried writting code but seeing as I am moderate this one is a little too advanced for me, a sample spreadsheet is attached for your reference.

The conditions is:
If any particuliar Row has the same Price (column M) & same Billing Account (Column J) & same Contract (column AA) as another row [/I] THEN simply delete the Entire Row where there is text found in Column AC

It may sound complicated, but with the sample spreadsheet it is easy to follow. Basically I am trying to delete the dup that occurs, I am dealing with thousands of rows of data so can't manually do this.

To sum up:
If a Particular Client has a case where the Account & Price & Contract are the same, I need one of the lines deleted, the line that would be deleted is the one with text found in AC. I originally had a macro to delete all rows with text in AC, but it was deleting stuff that wasn't dups, this is why I need to encorprate these conditions.

In my sample spreadsheet I highlighted in blue where this situation would happen, and if I were to run a macro it should only delete 2 lines, one from each case. ** in real spreadsheet rows where this dups appears may not neccesarily be adjacent to each other

This is a little too advanced for me, I will take whatever help I get and learn off you for next time. Greatly appreciate anyone helping me out.

Have a bless day.
