Very poor service from Makro online

Bought a product online on 30 April. Only after 3 phone calls and 2 emails I was informed that supplier do not have any stock. On 15 May they answered and said that transaction will be cancelled, and refund will be made. 3 More calls to customer service and every time it is the same story. Promises that somebody will get back to me was made every time. Still waiting for feedback from them. Even a written complaint to makrocare was not answered. This is by far the worst online shopping experience I ever had. The service supp**** by their online store can only be described as pathetic.
