BAD SERVICE FROM TAKEALOT.COM

The wrong product has been delivered to me and now that I want to return it and want the correct one delivered, they first need to investigate why the wrong product was delivered.

First they say it should take 24 hours to investigate, currently it has been almost 48 hours and still I have no update. Secondly, I did not make the mistake by delivering the wrong product, they can bring me correct one and collect the wrong one and still investigate where they went wrong. Why should I "pay" by waiting for them to figure out what they did wrong? I think this is totally unacceptable!!

Very disappointed with the service as they can't even tell me when I'll receive the product I ordered or how much longer the investigation into why they delivered the wrong product will take.
