No show - poor customer service

Phoned them on 06 March to make an appointment for a technician to quote on the repair of my washing machine. Appointment was initially confirmed for between 08h00 and 10h00 on 07 March. Got a whatsapp message on 6 March to move appointment to 16h00 on 07 March. Had to take a few hours off from work to be at home for when they arrive. At 17h07, still no technician showed up. Tried phoning them, but their phone is off, and goes directly to voicemail. I would not recommend them, based on customer service.
