I phoned them today as 3 emails over 12 days have had no replies. My bill was there just not applied to my account, when I questioned why he seemed to imply that as my billing period was from first to last day of each month and my direct debit to them was set to be taken on first day of each month that their computer couldn't handle it, so I got them to change the direct debit date to 15th so that excuse wont wash for next month.This does seem to happen to me quite regularly.
There is clearly some issue.
They fix it very quickly if you let them know however.
