The following points contradict each other:
if I don’t feel 100% then I don’t see anyone.
can’t remember the last time I even had more than 3 nights sleep
Okay call me whatever you want.
I presume that's a preemptive comment because no one has called you anything yet but you have called the OP a cunt. It's good to see you've now apologised for that but it's shame he had to make it public on here where it could damage your reputation before you decided to apologise.
As you can see from all of my posts I give a good service.
I presume you mean reviews. While most of them are positive, there are a couple of neutrals:

You also have a negative review for your old profile (although again, the rest were positive).
Anyway, assuming what you've said is true I do think the OP should have been a little better with his comms but I definitely think most of the blame lies with you, for 2 reasons:
1) Once you'd confirmed the booking, you should have made it clear to him that he also needed to re-confirm before the day of the meet. I say this because when I booked you, which you confirmed, I also even said I'd re-confirm on the morning of the punt and you said that was fine. However suddenly you wanted me to confirm yet again the day before. Since you didn't warn me, it was only because I check AW often that I noticed, not everyone will check AW or their punting phone so often. Also, you forgot the time we'd agreed to meet (despite having said it repeatedly prior and it being in the confirmed booking request) and then on the day of the punt you forgot how long the booking was meant to be! It all worked out fine though (as per my review, which was your first on here for your current profile) but it relied very heavily on my comms being excellent. However, I appreciate your comms might have improved since then.
2) Once he didn't reply to your re-confirmation requests, you should have made it clear to him that the booking was now cancelled/not on.
Based on what you've said, I presume you accept the blame and will hopefully be improving your comms in the future.
