Have just been looking at the code of practice on www.safebuy.org.uk (represents a large number of retailers).  One of the requirements is as follows:

'2.4 The site must have clearly accessible details of the retailer’s name and address, phone and fax numbers, an email address and details of what information consumers are required to provide to pursue a complaint against the retailer. Consumers must also be advised of their right to no-charge mediation by SafeBuy.

'2.5 Customers should be charged at the normal rate for a UK inland call for queries relating to a transaction. Where technical support charges are made, either by the retailer or by a third party whose product or service is being sold, that fact must be made clear to the customer before the order is placed. Information on the cost of communication relating to technical support, where it is at other than the basic rate, must be provided. Hours of availability for all types of phone enquiry must be clearly stated.'


So have a look through their directory, you'll find loads of companies, with not a single one using 084/087 customer enquiry lines. 

Or will you?

Good spotting hoxne.

I noticed on their homepage that CPW are mentioned, so for a laugh I'm going to email CPW and quote them this and see what they say.  Honestly though as CPW are a big abuser of these numbers, I don't expect to get anywhere or even get a answer.
