Bad service

This is the worst service I ever received from a company. They called within 10 minutes of my enquiry to join, BUT oh my word, this is the 14 th of March, today is the 31st of March, they scheduled a fitment for the device on Monday the17 of March., still waiting... Then scheduled one for today 31 of March at 10 o'clock, still waiting. After phoning them and holding for 7 minutes. Received a WhatsApp message that the technician will contact me and the appointment is now for 12:30 I am still waiting. No follow up, no fitment. If this is how they operate, what will they do in an emergency???? No thank you. Please steer clear>
