Hi, I’ve been trying to order online but Worldpay don’t appear to be processing my order. If they have, I’ll have ordered twice(mistake) as it didn’t seem to register! Not sure what has happened as I haven’t had an order confirmation. Can you let me know if my order has reached you please, if not will do it by snail mail. Also, just want to thank you again for brilliant product which has made septic tank finally behave itself!
