I'm surprised that message irked you that much, doesn't sound that bad to me. Almost sounds sincere, rather than sarcastic.

I'm sure that was the intent. Maybe I was just mad I couldn't complete the task but somehow the tone of the message really angered me and I never forgot it. It just seemed sarcastic and condescending.

Don't try to be cute in your messaging, just straightforward and direct is my takeaway. Some people might appreciate the cute but others you might anger if you don't get the tone just right.
