Dear sir/madam,
Our sincere apology for the delayed delivery. It was never our intent to have you wait ten days for the order to be delivered. Currently we've had an influx of incoming orders with led to understaffed people to handle all delivery appointments and customer care on all communication channels.
Normally we can keep our promise for the next day delivery. Hopefully this won't keep you from placing orders with Coolblue in the future. If you have any other questions, please don't hesitate to contact us again.
Kind regards,
Cooblue
