Rivonia Bergens Appliance Repairs - beware!

Terrible customer service..Almost a month ago I contacted them about a freezer that was not freezing. They advised they need to test unit in store since I recently had it worked on elsewhere and it was still problematic. I have made over half dozen calls since then to get an update and each time I am told they will contact me back the same day but no one does. I requested approximate pricing of a part that could be the only probable problem and that too is not forthcoming. I cannot imagine if I actually engaged with thos company to sort out my freezer if I would ever get it back considering the total disregard and avoidance of the customer. Worst service levels I've experienced in a while!
