Duplicate delivery payment done and store refusing to refund the customer

In am so disappointed at the bad quality service I have received through Sifiso explaining that the company doesn't have a process to refund the customers for the duplicate delivery payment done.

Its unbelievable that such a company that sells such an expensive furniture can reap its customers money even after paying so much for expensive furniture it sells.

Such small basic customer services that will make me not to do the mistake of giving the company business in a near future.
