Makro refusing to deliver items purchased

More than 2 months ago on 12 March I bought dog food to the value of R950 from Makro online and paid for it the same day. To date delivery has not been made and neither have I received a refund. Delivery was supposed to have been within 2 to 5 days. I have sent 10 emails to Makro customer care and phoned their customer care at least 5 times. Makro ignores emails and simply replies with a generic email saying they are receiving "a lot more emails than normal". The one email in which Makro did respond a few weeks ago simply said they have sent a follow up to the store and await the reply from the store. Phoning the customer care line 5 times also did not have any results as nobody could assist me there either. I have now even taken the drastic step of reporting Makro to the GGSOI ombud for mediation, which apparently is a legal requirement before I can report Makro to the Consumer Commission. I have never had to report any company to any ombud or the consumer commission before. I have never used Makro online before, but I have purchased many items online before from other companies both local and from overseas. I have never experienced anything like this ever before. Goods purchased from other companies online have always been delivered speedily and when there was a slight delay those companies initiated communication to inform me about the delay. With Makro there is no communication from Makro about delays and the onus appears to be on the customer to enquire why there is a delay and when the new delivery date will be. But despite asking these questions, Makro has to date not been able or willing to advise me when delivery will be made. Neither have they offered to refund me. Makro has had my money for more than 2 months and has been drawing interest on it without honouring their part of the deal. Needless to say, that although this was the first time that I used Makro online, it was also the last time. As soon as I receive the items purchased or a refund with interest, I will immediately delete my Makro online profile and destroy my Makro Card. I have no intention to support a business who treats customers like this. Never before has it taken two months or longer for goods to be delivered after purchasing online from other companies. Not even for goods ordered from China. Takealot for example delivers within 1 to 5 days. But what is the worst is the fact that Makro ignores emails and phone calls. It shows utter disrespect for their customers.
