my OVHD decodor

I have had the worst exprience with these guys from makro in centurion who have just messed me around with my OVHD decodor which i have sent in for repairs over a month ago and was told that i will be getting either a refund or a new one which never happened my husband called them last week to find out whats going on and there was no joy he was transfered to numerous departments and spend along period of time holding so someone could pick up he was passed around various departments and finally when he got to speak to a manager he was told that he will be contacted within the next hour which never happened so on friday the 13th we took a day off from work just to go to makro and speak to someone who can assist us and we spoke to a manager who was very apologetic and said that we should give her till monday she was going to call us and we have still not been contacted!
