AIBU to be annoyed at the above company, for not showing up to replace my old Electricity meter today. They gave me a 6 hour window from 12pm-6pm to do a 20 min: exchange . I have stayed in from 8am , it's now7-35pm, I tried emailing them but no luck on a response . I had two calls from them in the week , checking that I would be home at the alotted time.
