Only two that I need to tell you about.
In the first one a PCN was cancelled because the PayByPhone system was down and there isn't a viable alternative in most places, meters now being as rare as hen's teeth. I heard this week that the owners of PayByPhone are putting it up for sale as it is not mainstream to their business and even taking 10% of the payment, as they roughly do in Barnet, it loses money. All I can say to that is they haven't put their technology together very economically if they can't process payments for a single digit percentage.
The danger of relying on just one form of technology is that the day that armageddon hits the phone network, there will be almost no income for the council.
The second PCN was cancelled as a blue badge holder had one without an expiry date on it and there was, apparently, no reminder system to forewarn you that you need to renew.
Keep those Appeals coming.
