Disappointed with my HiFi Corp experience

My online order has been on hold this entire week, even though I received an email DAYS AGO to say it will be cancelled due to insufficient stock. Why has the order not been cancelled yet? Absolutely pathetic service regarding this entire order. No-one even asked if I would like to choose another TV in the place of this one. Just said my order will be cancelled, and now I must wait 15 days to get my money back that I paid for this TV
