Poor Technical Service

We have booked a service on 2 of our Tumble driers I have explained to your consultant that we are a hospital with long staying patients that needs to wash their Laundry pls book the service for 9am. He committed the technician will be on site 9am. 10 am i phoned as the technician did not show up, he said he will find out where the technician is and let me know, which he did not do then the Technician phoned me to 12pm to let me know he will be on site 2pm but then only shows up at 2:45pm. This is unexpectable!!! we run a business and i can not let patients wait the entire day for your technician to someday show up! Service call : 32674
