Poor poor service and communication - Taking people's money

I ordered a bud earphone on 7 May worth R330 and paid R75 for delivery. It reached me on 9 May but the completely incorrect item. This was after it said "In stock ". I logged a return product with the option asking for the correct product to be sent. They collected, and today 16 May reversed my R330 into a Takelot credit. My complaint is that it was not my fault that they sent the incorrect product, probably because they never had stock of the item I ordered. Now telling me sorry no stock. But why must I now pay again for delivery and why cant I get my R75 reversed to credit as I got nothing at all. Looks like this is how Takealot makes money. Accepts orders knowing they dont have stock, then rob people of their delivery money so that they can be charged again. I hope they will email me as I emailed them as well. Their is no call centre you can call to speak to anyone and just a bunch of stupid questions that does not help at all. This is a bunch of ****** and I'm sure it happened to other people before. For such a "renowned" business to make dealings.like this is totally unacceptable. They blatantly just took my R75 delivery fee for absolutely nothing. One star, and if I could give a 0, it would've been.
