Not honouring extended warranty

2 Weeks back I called on Makro about a fridge that was not working. the manager from Makro Wonder boom contacted me few minutes later, explained I had a extended warranty and that they will escalate the issue to the service provider to come and have a look at my fridge. 3 days later 2 technicians from Panaservice arrived just before 6 in the afternoon. just opened the pc cover said it was invested, they would write a report and someone will contact me. next day late I contacted them and they said the case is with Makro head office , phoned them, they ensured me I would get an email with results and report. after 2 weeks no email. phone nr keeps going on voice mail. ordered myself a pc board(@a huge cost). replaced it.... my Fridge still is not working. I have tried again to contact head office no answer. they failed to inform me of the results and the technicians did not bother to have a look at the issues I explained to them.
