Drunk technician

I called to follow up on installation- call centre agent was extremely rude. Fast forward to day of installation: Technicians were booked to come at 8am. At 08:30 still nothing. I reached out and was told the technician is 30minutes out- he took longer than expected at a different installation. I however advised that I won’t be in as I have to work which is why I booked that time specifically. After much up and down they eventually booked a 4pm slot for me. The technician called at 3pm to tell me he was on his way but I was not home as we had agreed on 4pm. He offered to wait as I was about 20 minutes from home. When they eventually made it to my house, one of two technicians was REEKING of alcohol. From beginning to end it was not a pleasant experience from this company and its sister company Britelink MTC.
