Worried about aluminium window installation

[JenB]

We have just had new aluminium windows installed and I am worried that there are things which are not right .  Is it normal to have chunks of the frame carved out as drainage holes and leave the aluminium exposed on the edges!  Also a lot of the beadings are scratched from installation.  Is it normal/successful to have these repaired/touched up?  They are supposed to be coming back but unsure whether I should push for new beading?

Regardless of beadings I would tell them to replace the frame The fitters shouldn’t be cutting anything off the frame All the drainage is normally done at manufacturing 

Very rough work

They should make new all the scratches caused during installation. My installer (Passivlux) have no sense of urgency to do this (or anything else to be honest), but I am pushing them to complete this before signing off the work.
