Dealer Or No Dealer?

21 Plate 1.5 Petrol Estate. 25000mls. Bought it with 3300mls on it as an ex demo' in late 2022 from local (ish) dealer. First 4 services chucked in with it, along with my first M.O.T. Had M.O.T in July, notified that all discs (and therefore pads) need replacing (which they do, as they're lipped) and that air-con service due.
Car told me at the weekend that an oil change service is due. Normally the annual email from the dealers arrives before that notification pops up, but not this time.
Rang them this morning, receptionist told me "nobody on service desk". Took some details, said someone would ring me back today. They didn't, which got my back up a tad.
Question is, should I sack them off, as they're an hour's drive, and find someone more local who would no doubt be cheaper, or is dealer service history worth having for the car? My experience tells me that this is a very fussy car. Is an inependent likely to have the right knowledge and specialist equipment to keep on top of things (software updates for example)? Plus, it's a minefield finding someone reliable.
Following a mini-stroke I am unable to do any work myself so I'm completely at the mercy of everyone else. Obviously, I'd like as not save a packet leaving the dealer but there is a sort of peace of mind that using them brings.
There is a VW dealer a couple of miles from me under the same corporate umbrella. Would they be set up for Skoda and worth a look? It is virtually a Golf, isn't it?

Any thoughts and opinions (good or bad) welcome, thanks.
