I was having new gas cooker delivered on a Monday a couple of weeks ago, and so wanted someone to install it on the following day. They quoted a good price and said they could come at 9am on the Tuesday -- my preference -- and said they would also take away the old cooker for a fee of just £5. "Perfect", I thought, and made the appointment.
Tuesday 9am came and went, and at about 10 I called, but it went straight to voicemail. I left a message saying that if they've had a family emergency or something and would not be able to come, I would understand, but I would appreciated being told whether or not to expect them.
I never heard from them again: they never showed up, never apologised, never provided an explanation. Nothing.
