Poor returns policy

Purchased a car seat from chelino gateway. Wished to return it because we wanted to purchase a matching set for the mum to be.. (stroller plus seat). This was only 3 days after the purchase. Seat is unused and in original packaging. Store will accept return on condition we use credit at store. No refund. I appreciate that different companies have different policies, but this is just not right, especially for companies that brand themselves. So we'll keep the car seat, purchase elsewhere in future and make sure we pass on this experience to all potential customers.
