Takealot said dispose now they complaining to credit.

I placed a return and takealot said to dispose.of the item then they would credit my account. It's been a week and it's not been credited. I called and asked why. They said it needs to be returned and they want proof of the email that said to keep it or dispose of it. I had logged 2 items to be returned and credited but only one was picked up and they take forever to credit my account. Now I don't have the packaging for the one item and the lady said they might not accept it or she will schedule a pick up or she can't see the email that says keep or dispose. Why is it that I always have so much problems with takealot when other people just get hassle free service. I want the credit for both my products or better yet. Refund my bank account today because I'm tired of this terrible service.
