Hello, the appointment was [date and time], and the worker could not enter after arriving. The circumstances known to me are [summary]. Please check arrival and contact records, the reason access failed and any work actually completed, and explain the charges for this visit and their basis. Separately confirm whether it can be rebooked, who confirms it, any new charges and how access should be arranged. Mark disputed records. This enquiry does not confirm that the work was completed or accept a new booking.
