No show Electrical Doctor

I booked an appointment for Electrical Doctor earlier this week to install a hob in one of my Fish Hoek apartments. They confirmed for 09:00 this morning (Friday 10 October) but did not pitch up. When making contact they apologized and said they would be here by 13:00. it is now 16:30 and still no show! They are not replying to my WhatsApp messages or taking my calls. Never again!!
