Barclays Wealth gripe

Barclays Wealth had flowers in May for the Hay festival. Everyone else pays with no problem. They ordered so late (two days notice from confirmation to delivery) that I had to invoice them for immediate payment rather than requesting money up front which is usual practice for a new business customer. Hurrah, it has only taken 9 weeks and I get an email today saying they will pay my designated bank account....... sadly it doesn't seem to say when they will pay my designated bank account.....perhaps today?
