How much cash is being lost from the broken parking machines at Hastings Country Park?

Reference parking at Fairlight Park. The parking machines stopped working at the end of September and have remained padlocked shut since.

A week or two after they stopped working some paper signs went up saying phone a number with your mobile to pay for your parking – this in a reception black spot.

The signs were quickly ripped down and have been missing since late October never to return.

Two questions: 1. how much money must Hastings Borough Council be losing each and every day by not mending their machines?

And 2. as I have a permit, can I have a refund for the money spent when the parking is de facto free?
