no help at defy to fix their product under warranty

I bought a defy airconditioner inverter from Makro springfield durban in February 2017. they sent one of the approved technicians to install it and this guy Leon ********** 546 continued to service it etc etc. now i am getting a FF fault and this guys number is non existent. i looked on my warranty book and the service number for durban is also non existent. i eventually phoned the defy call centre to book the fault as its still under warranty on ********** 339 job number was created ********** last week 23/01/19. i phoned today and they gave me the technical number for Ashlene to follow up ********** which i was told the call centre did not send the email so i had to call and arrange that to find that Ashlene said the call out fee is R400 as they are not associated with defy and its warranty but defy contracts them out so how is this my problem. i got told to call a Tommy Gordon which is unreachable then i got transferred to a durban manager which was unreachable and a lady called Lynn said she would get this man to phone me after i told her my story and no one has phoned me. keeping in mind my warranty ends in February 2019. this is ridiculous and all i want is for someone to come out and fix the fault. i will never recommend anyone to buy a defy product again.
