Makro - shocking telephonic communication

My complaint relates directly to their telephonic communication. I took a faulty item into Makro a couple of weeks ago for repair. I received a missed call from the repairs department a week ago, however, I have tried on numerous occasions to return the call - contact the department telephonically, however, it is impossible to get through to them. I am either cut off when the receptionist finally answers the phone or when I was fortunate enough for her to take my call and transfer it to the department concerned, I was left 'holding on the line', having to listen to their promotional gabble. In one instance, I waited twenty three minutes before I put the phone down. It's incredibly frustrating and does nothing to encourage me to want to shop there, for fear of having another faulty item that I may need to return but end up having to personally visit the repairs department in order to monitor the status of the repair!
