Autosleeper Spares Dept. unavailable

I have just logged into Autosleepers "spares" to view their quote for a fresh water cap ordered last Thursday.   When I click "purchase" a message reads :- an error occured.....our technical team have been informed......please contact seller.     I phoned Autosleepers and get a message saying there is no one to take my call please use their website!      Does anyone know any reason behind this.   They can't all be on holiday as my request must have been dealt with early this morning.

I'm assuming you used this number - 01386 842 630 - and rang after 9.30 this morning.  
Parts dept open 9.30 to 2.30 Monday to Thursday.

Yes that's the number I used and I thought it was after 9.30 but perhaps I was too hasty as I have just been successful on the telephone.   Thank you for replying.
