Very unhappy lifelong customer

I ordered an item from Takealot that was delivered to me. After i opened my box i found the boxed item opened, the box damaged, and the product was messily shoved into the plastic bag. The box also dit not have all the items inside shown would be included with my order. Not sure if the items were removed, hence why the box was opened, or if the image on their site was incorrect, falsely advertising the product. I sent them a request to replace my item as it was incomplete and my box was clearly opened. Once the item was collected i received an email stating i had 24 hours to reply to whether i would like a credit as they could not replace the item for me anymore due to the supplier not having any more stock. Within a half an hour i received another mail stating my account was credited. I sent them a mail regarding my unhappiness with their service as this was the second order of three orders this year i needed to return from them and both times they were unable to supply me with a replacement. The first order contained speakers in the box of the item i ordered's box. I find it shocking that a company of its size does not pride itself in its customer service and product quality anymore and if you communicate with them you receive no feedback. I have been a customer since Takelaot was established yet they do not seem to care if they lose clients due to damaged or missing items and care less if incorrect items are delivered and then are unable supply you with the item ordered.
