Two purchases paid for. Nothing received after 3 weeks.

1. On 23 May I purchased a DVD player and paid by credit Card. My credit card has been debited, but I have not even received an order number yet. I cancelled the purchase but have not received any acknowledgement or refund. (R440) 2. On 24 May, I tried again by purchasing another DVD player and paid R582 by credit card. Order ***. I have received some very weird emails from House&Home, but no DVD player as of 9 June. House&Home does not respond to my enquiries.
