Disappointed

So disappointed in Dis-chem, I placed a order for delivery on Monday. No updates received. Yesterday I sent a online inquiry.... no answer. Today I call and I'm placed on hold for over 6 min just for them to tell me they will get someone to call me. Receive a call back they tell me 3 of my products are out of stock. They could have called to tell me this.... they refund the amount for out of stock products to store credit. I go to check the refund and the store credit dissappear. I call immediately... . Im still waiting for a call back. So where has my refund gone?
