Makro online can not process payments and *****l money form you

I placed an order on Makro's online store for R30K. I paid via OZOW, and during payment, an error message appeared. I reverted to redo the payment, but then noticed that the amount had been deducted from my FNB account, so it was paid... yet the Makro site still shows it as not reflected on their side. So I paid R30 K, they took the money...I emailed the online customer service and made two phone calls. They told me it would take 8 working days to get back to me. However, they literally stole R30,000 from my bank account, which will nw be in their account for at least 8 working days, earning interest on my money. It is theft and *****!
