Aquatech Pool Services - Can't keep to appointments.

Left a message on their website page Monday 24/06/2019 night. Tuesday morning a call and appointment for 4.30. No one arrives and no communication. This morning a call if someone at home now? No, there was no one at home. What a cheek. New appointment for 4.30. They arrive at 5.35. Starting to get dark and they want to look at my pool? Take a hike. If they can't keep an appointment, hate to know what their workmanship is like! Useless.
