No help from Makro

Have had the worst experience with Makro Marketplace, had I known I wasn’t buying from Makro I wouldn’t have done so. I have been waiting for my refund since June and it has become such an inconvenience because I have to allocate time weekly to call and explain the same story over and over again to the care people or managers. I bought 3 heaters which were to be delivered in 2-5days , on day 6 I made an inquiry and was told the supplier was out of stock, mind you it was in winter and we needed the heaters asap, so I cancelled the order and bought the heaters elsewhere. Now the issue is getting my refund, I’m really disappointed because Makro is a big company and to be going up and down and not getting any feedback or help is very bad.
