Waiting period is unacceptable

I have a problem with a Microwave that I bought. I lodged a complaint with Makro and must say they were really quick and helpful to collect the microwave from my house which I really appreciated as I understand they dont normally do so. But that was 06/08/2015. So then if it was collected then why is that it was only booked in today 12/08/2015 for an assessment. What happened about Friday? Both companies operate on a Saturday but I wont let that break my head. Fair enough Monday was a public holiday. But then what about Tuesday? My food is bought and placed into packets at the beginning of the month. Every packet is made in such way that I can have dinner of it and then to warm up some for a quick and easy breakfast. But now thats where the problem comes in I cant warm it up because I have no microwave and I cant stand cold food. So that gives me 2 days that i had to through food away because of a broken microwave while I had it and now it gives me 5 more days while Makro had it and who know how much more while samsung has it? I just feel that it's unacceptable that Makro took so long before booking it in leaving me to through away food everyday. I am loosing money every single day
