Double yellow line AND road sign

[100]

I parked overnight on saturday to sunday on a double yellow line, as there was a sign stating that parking was prohibited between 8.00am and 6.30pm Monday to Saturday. I was issued with a parking ticket at 9.30am on Sunday...WHY ? Any ADVICE gratefully received...

I think you may have been misled or misread the sign - see the middle sentence - this is from a government website:

You MUST NOT wait or park on yellow lines during the times of operation shown on nearby time plates (or zone entry signs if in a Controlled Parking Zone) � see 'Information signs' and 'Road markings'. Double yellow lines indicate a prohibition of waiting at any time even if there are no upright signs. You MUST NOT wait or park, or stop to set down and pick up passengers, on school entrance markings (see 'Road markings') when upright signs indicate a prohibition of stopping.
