Worse online bedding company

I have bought a mattress online, 24 hours later I discovered it was not what I wanted and cancel the order. I instructed verbally and in writing to cancel and refund. I was told I will only be refunded in 30 days. According to the Consumer Act Suppliers are required to return payments received from consumers, within 15 business days of receiving the cancellation notice. 1. Consumers have the right to cancel any orders.
