Unprofessional service

Buying a house with under this development started off well but is slowly turning into a nightmare, Im losing money due to the delays with fixing the issues in the house I bought, Its been over 4 weeks since my first inspection of the property having issues like waterproofing, electricity and the painting I mean if one takes a week to sort out Im sure by now all of this would've been sorted but we still stuck on stage one, its really dissapointing to be out here escalating this issue here I feel after I met with the lawyers the development kind of tickboxed and went out to look for more customers instead of ensuring that new existing customers are sorted out before giving the cold shoulder I am really considering dropping this whole thing ,I'll take whatever penalty or credit hit I'll get but this is really getting to me
