Answering the original question, I've not noticed their advertisements in ME for a long time.
The name "Parkside" appears used by half the on-line commerce world, but wading past all the rhubarb reaches parksiderailways.co.uk.
I assume this is the company meant.
It reveals still, only the locked home-page the owners published early in the pandemic, apologising for the Covid situation and their own unstated but "previous" illness forcing them to "…close until things start to get better" ; to protect their families, they add.
So not hopeful….
