Ok, I did not receive a call saying when he was coming. I asked he tell me when he was turning off power as i was on an important Teams call, he did not and i got booted off. I asked if he was going to tidy up the mess and he said "thought you would do that" He then asked for a brush and i told him I would do it. When I pulled the tethered cable out to chase i noticed the unit was covered in brick dust. He obviously fitted the bracket for the holder after the main unit and all the dust just fell over the unit. i had to pick up screws brick plaster and dust and hoover, really untidy get the job done and get away attitude. No professional look very untidy in appearance. I do not think the cabling is neat it is not straight, bit of an eye sore in my opinion. Happy to send pictures. When I asked him not to switch powder of as i said i had a very important call he said " this is important to me" I said i have had the call scheduled for weeks he said " this has been scheduled for weeks and all he was concerned with" Not very pleasant at all
