Cape Gate branch - no feedback regarding mark on base

Purchased a king sized bed at your Cape Gate branch on the 5th of June. Delivery was scheduled for Friday the 6th June but then received a call as to whether delivery can be the same day on the 5th June. Upon delivery we noticed a mark on the base. Delivery guys said all we need to do is write on the delivery note that we are not happy and that an exchange must be done. This we did. By the 11th June we had still not received a call. This was when I contacted via whatsapp. On the whatsapp line, I was told that I should contact the store and then they provided me with the email address. Bearing in mind that you have not equipped your delivery guys with the necessary knowledge to inform your clients of the correct procedure to follow. Our instruction from them was to just write on the delivery note and it will be dealt with accordingly. I emailed the store at 11:02am on Wednesday the 11th June, to which I still did not receive a response. Now, I'm at a point of actually just requesting a return of this entire bed and have the sale cancelled and my money returned if this is not dealt with urgently. There are other places where I can purchase a bed, you are not the only store. It's actually sad receiving this kind of service when you are a returning customer.
