As far as I know the delivery worked well. No-one has complained to me.
Invoices arrived on Saturday 7th, at least mine did. That's a bit short notices as they expect to be paid by the 10th. Get your skates on. Notice that the invoice is at a higher rate with a discounted amount in smaller type below.
I have had one member mention that the invoice somehow neglected to include the credit card deposit he had already paid. You might want to check for that error on your own bill.
