Makro Online

I bought online , part of my purchase was delivered within a 3 days the other part last status said Your order has been handed to the Courier . On 30th I followed up on the order they are telling me that it's out of stock but the items still shows on online store but I've been told it's out of stock even now those items still available online . I have send them an email same day on the 30th no responses and today it's the 5th , I'm so disappointed in such service when I login into my profile I see refund Initiated but no-one contacted me . Now i tried purchasing the items again the price displayed it's not the price at the check out , on the checkout it's more . When I enquired they told me about the supplier which how is that my problem I believe if something is not in stock it should've removed from the online store and it should have notified me when paying for it not that I get email confirming that it has been handed to courier after days of not receiving it when i follow up with them that's when I'm told it's out of stock . So unhappy
