Shocking online shopping experience - avoid at all costs!

I had an awful online shopping experience. Tried to return an item I ordered. Logged the return on their system on the 19th of Feb. 2 weeks later, I have not had any response from Makro on the status of my return. I have called the contact centre 8 times. Each time I was told there was a backlog, another department looked into it. Makro is holding onto a large amount of my money and has been entirely non-communicative. It is impossible to talk to a supervisor. Shocking online shopping experience - avoid at all costs!
