Ordered a large order on Thursday night, paid for NDD guaranteed by 1pm, upon ordering I asked the seller for my tracking and have had no response just the automatic “sent” message, I’ve just watched the postie deliver to 3 houses by me but zip back off, have now asked seller for my tracking 3 times as I paid for NDD guaranteed by 1pm, still nothing from the seller, postman deffo walked right past my house, any advice???
