Well, this all depends on what's been agreed...you said you "booked" three hours, but did the person who took the booking come out to your house to see what it looked like and to meet you? If not, and this is on them, you're not starting off on the right foot to begin with.
Anything such as inside microwave and limescale on taps is the exact thing which should have been discussed at the initial consultation...insides of microwaves are, in my experience, the sort of things that have to be requested, and limescale is a difficult one (no matter how easy it might be to remove) as it takes time and the process can easily damage fixtures...but again, a consultation was the time for all this to be discussed.
Again, this is all in my experience and by no means that of everyone, but ordering cleaning from a company where the cleaners are "booked" and work in twos or threes etc. is only ever going to be people coming in to "go round the house" and spruce it up...fine if that's what you need to keep it going, but for an on-going routine clean with different parts of the home being given more attention each time so that all of it remains continually clean, you need to hire someone who works for themselves, alone.
And don't get me wrong, that's easier said than done, and can be hugely unreliable, but there are people out there for whom cleaning houses is their focus and who take it very seriously.
However, from your post, you said Not really knowing what to expect from it I guess but I really thought the basics would have been done...while I totally get that any new experience is one where you need to try it to see what it's like, when it comes to cleaning, you already know what needs doing because it's your home, therefore ideally you need to express what it is that you need, rather that wait to see what they offer you...a good cleaner who works with you one-to-one should be able to come in and do the things that you aren't doing, whether that's a general weekly clean, or a few hours every month to do additional cleaning jobs that you never get round to doing.
My late mother always ran a spotlessly clean house, but towards the end of her life could no longer manage a vacuum cleaner, which really distressed her. She had someone to help clean, and her instructions were basically "please come every two weeks to thoroughly vacuum every inch of the floors, mop the kitchen and bathroom, and if there's time maybe wipe out the fridge (etc), but above all, don't scrimp on the vacuuming as this is where I need the help".
She was lucky as she found a young lady a few doors away who was happy to do what she wanted, to the standard she wanted. Other people are much less specific in their needs, so be clear on what yours are, because someone could spend all day cleaning your house and still not do the parts that are on your wish-list, so tell them what they are.
