It does sound ridicules doesn't it. ZEN are highly recommended as a Broadband provider and consistently come top of the list in test for, speed, reliability, and customer care. They also quote a time of five days from placing order to delivery of modem and account going live.
click here for ZEN, and click here for the ADSL guide to providers. If you click on the "Compare" button, left of screen you can compare as many ISP's as you wish. ZEN seems to come top in each category each month. Good luck with the move, hope all goes well for you. Regards. j.
