Hi Fi Corp online is a rip-off

Never ever buy online from Hi Fi Corporation. They are very quick to take your money without having stock of the item you ordered. They guarantee delivery between 3 to 6 working days then send you an email on the 5th working day informing you they apparently have no stock. But your refund will take 7 to 10 working day or 15 days with Capitec. Ridiculous. I don't have funds to purchase at another store now. I now have to wait for up to 15 days for my refund which is utterly unacceptable
