Makro online make empty promises about refund waited 2 weeks already

Dealing with the Makro online retail department has honestly been one of the worst online purchasing experiences of my life. They blame third party suppliers for taking weeks to collect items that were incorrectly delivered and now I have been waiting for my refund for more than two weeks. I spoke to Martin Hlongwane who promised me my refund for my purchase of more than R12k would reflect in my account by today but it doesnt. I really dont know what else to do. I will NEVER buy anything from Makro online again and I will warn every single person i know not to deal with them. PATHETIC in the worst sense MAKRO. Stop blaming your third party suppliers and get a freakin clue about what service is.
