MAKRO DELIEVERED MY ORDER TO WRONG ADDRESS AND I AM PAYING THE PRICE FOR THEIR MISTAKE

Placed an online order on 19th April (Order number MAK***) and a couple of days later I received an SMS notification to the effect that my order had been successfully delivered, despite me not having received and signed for it. After contacting customer service, I was told that my order had been delivered to the wrong address and would be retrieved and delivered to me within 3 days maximum. It's 7th May, and I am still waiting for my order to be delivered to me. I call every day, and I am always promised that they are working on it. In the end, I asked for a refund so that I could buy elsewhere, but was told I cannot be refunded until they locate the original order they delivered to the wrong address. In other words, I am now being punished for their mistake. This is the worst service I have ever received from an online store.
