Charged for Saturday delivery to a postcode where this service is not available. Attempts to have this difference refunded have been met with reasons that follow no logic. The service I paid for was charged at £25.91 a premium of £16.02 on my normal 24hr service. They refuse to refund this amount claim the service was fulfilled within the time frame! Monday is not Saturday, the service wasn't available yet they take the payment and then won't give it back. Wasted so much time trying to get them to see logic, account will be moved to a different courier as soon as possible. Great friendly drivers, absolutely useless customer service! The guy who managed my account will not even respond to my polite requests for help with this matter. AVOID!
