bad service

I was approached by them for a device , the appointment was set for 10 in the morning ,the technician never contacted me to notify me he has a double booking , I had to spend almost an hour contacting them in December ,fast forward to January they reschedule again and again no technician , no call . Called them and this time round the excuse was they were unable to reach the technician, Until today I'm still waiting on them. They send messages saying they called.
