Pathetic service

15/06/2015 - OEG technician was booked to repair my Samsung washing machine. Did not arrive, no answer at call centre when I tried to enquire. 17/06/2015 - technician arrives, can't resolve my 2 problems. Tells me to book another call out and leave laundry for next visit so he can see machine in use. Several attempts to reach call centre , either phones go unanswered or cheeky service from operator. Booking for repeat visit not carried out as scheduled. 01/07/2015 -2nd (different) technician arrives, problems not resolved - laundry specifically set aside for technician completely untouched. No feedback, voicemail for manager ignored. 08/07/2015 - scheduled booking for new part to be installed - technician does not arrive, call centre has not phoned to apologise/reschedule to date - despite being fully aware of poor service received to date. Summary: 4 bookings made, only 2 carried out. Almost a month later -machine still problematic
