Thanks for your email. I've had a quick look at your order and can see that your order was dispatched on a next day delivery. According to the tracking information, the delivery failed because nobody was present to sign for the consignment. When a delivery fails, it is automatically attempted on the next working day which in this case was the Monday.
If you have any problems in the future with deliveries, may I ask that you contact us direct and we'll speak with the couriers on your behalf. My email address is support@guitarguitar.co.uk or you can contact the office on the telephone number provided on your order confirmation.
Please let me know if there's anything else we can do for you in the future
