Serious Lack of Experience

I purchased a fridge from Makro, it has not worked. They sent a technician out to have a look, and he advised that the casing was cracked and there was a water leak that could not be repaired. They sent through a credit note to Makro to uplift the fridge and replace it. I have been trying since Friday to get an answer from Makro on when the replacement will be delivered, I spoke to one person this morning who promised to call me back in 2 minutes, it is now 9 hours later, at lunchtime I spoke to another lady who promised that one of her sale people would be in contact, I am still waiting. You cannot get through to the National Call centre. Service is a shocker! Last time I purchase anything from Makro.
