False Advertising.

I bought a Convoluted foam (egg-box-foam) Queen, from www.bedmat.co.za on line, the price stipulated on their website was R645. I followed all instructions and made the EFT. There was no mention of further costing for shipping. This morning they called to tell me the price for this products is wrong and tried to charge me a further R250 for delivery. The consumer protection act states that this is not okay. They then emailed me and asked for my bank details to give me a refund. I don't want a refund I want what was promised, A Convoluted foam (egg-box-foam) Queen sku:con91 (order: 19152) delivered to my door for the price of R645.
