M135i wheel alignment question

[Smongles]

First post here so hope it’s helpful!
I have a 63 plate m135i. I recently changed all 4 tyres at the same time to Michelin pilot sport 4s. Whilst having them fitted I had 4 wheel alignment done.
It took ages (2.5 hours) and at the end was told to come back in a weeks time as it may not settle as they used heat.
I’ve been back and there was much more adjustment made.
I asked for a printout and it say 1 series sport up to 2014 E82 E88 at the top.
Well aware mine is an f20 I questioned this and was told ‘they are the same underneath’

I’ve sent an email to their head office asking for clarification.

It’s a major uk chain. Ive already been waiting 4+hrs in the branch for the tyres and alignment to be done. Not sure I trust them with any more given service so far.

I have scoured the internet and am none the wiser so thought I’d ask here for some opinion / advice.

Thanks
