Disgusting service

Bought a heater when I got the heater it was not what I wanted, tried to return the next day was told at Makro strubenvalley that they couldn't assist as they didn't have stock of it logged a return call, was told it will be collected Saturday, 2 days later nothing when I call to follow nobody knows anything other than it's been delayed. I want my money and yall better come collect this heater I will never buy anything from Makro online the service is horrible
