Bad service

I purchased an electric fan online,only to find out it has incomplete items I've logged a complaint manier times.ive called makro every week they told me that they are aware of the problem and they will do a refund within 3 to7 working days. Right now it's been a month, I've been making follow ups with no respond from their side.I have more than 10 emails that I've sent regarding this matter. Still I'm struggling to get any response from them.Im so disappointed in Makro I've trusted them since it's a big retail in SA.I need my money back please!
