Then that page is lying. I called them at about 12:00 on 01706 902000 and pressed 1 for sales. Got a message saying they were closed.

Hi there, I've just checked on this for you the 01706 902000 number for sales / customer services numbers are not open on sundays. Their extended hours are:

Monday to Friday: 9am - 8pm
Saturday: 9am - 1pm

I am under the impression there was a trial on another number with sunday hours as well though I don't know for certain if this is still in place it was however not for the sales and customers services number.

I think there was Sunday opening on the weekend after the initial announcement to existing customers (when the 'Order Now' buttons were an instruction to call sales on a special number). By the time we got to last Sunday (one week after), mention of Sunday opening had not been removed from the page. I posted that sales were open in good faith, mirroring what the web page said at the time.

The page now accords with the times you state, Aaron.
