If you were having work done spread for a few months in dribs and drabs because builders were waiting for supplies or for jointer to get back to them etc, would you expect a phone call to let you know when they were coming to carry on with the work?
For example I haven’t seen the builders who are doing me a new drive for weeks because they couldn’t get the slabs I wanted, which is fine, they said they’d keep me updated. Haven’t heard a thing since start of September but they’ve turned up this morning at 7am asking me to move my car and DH car so they can get started. They’ve done this multiple times since starting the job and they use my house for access, so I need to be here, meaning my plans for the day are ruined 
I’ve asked them constantly to communicate with me and I’m getting so fed up.
