Hello.
I would 1st take this up with the fina e company.
You are probably in a position to still reject the car.

The OP says it's on a lease. Different rules apply. And if the OP has had the car on a lease since 2017, I'd have thought there's unlikely to be a right of rejection in any event.
Saunders1712 - the first place to look is at the terms of your lease agreement.
Have you contacted the lease company? Technically, it's their car, and they might have interceded on your behalf with the repairers, and/or provided you with a replacement vehicle themselves. Nationwide Vehicle Contracts provide this useful guide for their customers on what to do if a lease car goes wrong:

You refer to £400 "for the service", but your post doesn't make clear what this charge is for. If you're referring to the annual maintenance service, and if, under the terms of your lease agreement, you are responsible for servicing the car at the manufacturer's recommended intervals, then yes, the cost of this falls on you, even though you've not been able to use the car while it's been under repair.
It's a bummer, but cars go wrong, and when they do, the hapless owner/lessee usually ends up worse off, whether financially, or in terms of loss of satisfaction. But if I were you, I'd be pressing the lease company for a sweetener (eg, extension of the lease for 3 months, to compensate for the fact that you've been without the car for that period). Having said that, if you've not given them a chance to sort this out for you before now, you may not get much sympathy from them.
PS You posted in the Barchetta section. You might try reposting in the 124 Spider section (surprisingly, there isn't a separate Abarth 124 Spider section on here, although there is one for the Abarth 500, Abarth Grande Punto, etc
Someone upstairs at FF is a bit slow off the mark, methinks, or maybe
)
