Makro lies about their prices to make sure that you spend money online with them

I placed an order for a birthday gift on Saturday, all set to receive it by Thursday. Makro then send an email on Tuesday saying that they made a mistake with the pricing, pulled out some BS statement from the CPA, and said that my order will be cancelled and they will send a voucher within 24 hours. I did not receive a voucher. And I do not want a credit of my money into my Makro account! I want the product that I ordered. This is really poor service, and I did send an email to their customer support team and have not received a response. Why would I want Makro credit when I will face the same situation - you cancel an order 48 hours before delivery and say "oops we made a mistake". Please just give me my product!
