The only number for the above company, given on the website, is

0844 371 8021

They have not replied to an e-mail sent at the beginning of the week, and I wish to check on changing a booking. 

Any assistance would be greatly appreciated.

Thank you.

If you are contacting them about something you have already purchased, and they provide access by telephone for this, Regulation 41 of the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 require they provide an 01, 02 or 03 number for you to call.

Where telephone access is provided but you have to call an 084, 087 or 09 number, Regulation 41(2) gives you the right to a refund of the call costs incurred over and above whatever the call would have cost had it been made to an 01, 02 or 03 number.

The regulations came into force on 13 June 2014.

You can also report the non-compliance to Trading Standards via the Citizen's Advice national Consumer Helpline on 0345 404 0506.
