Whilst I do not expect to have to go through their web page to establish if they will respond to me or not, I do appreciate that these things happen.
If they are having issues with their phone lines, given they are for sales etc, one would have expected a big red banner accross their page alerting potential customers. Otherwise, this sort of thing happens.
Either way, I have subsequently left them two messages after the phones were fixed and neither have been responded to. The last was two whole days ago.
