Ordered 3m x 3m 50 series in grey online but unfortunately not in stock for 3-4 weeks. Informed via email around 3 hrs after online order and offered alternative colours which I declined as only wanted grey. Informed that the website does not show live stock, which is a shame these days, but the customer service was otherwise excellent. Full refund completed next working day with a copy of the SagePay transaction sent by email. As I feel these reviews are more about service than goods I have given 4 stars (4.75 would be the choice, but not possible). I would have gone a full 5 stars had live stock been in place as everything else is there! I will return at a later date to see if the availability has changed and order one but, for now, I have gone for a cheaper option elsewhere to get me by.
