You tell me what went wrong! I waited in ALL DAY for a GUARENTEED delivery only to get an notification later in the day to say Royal Mail tried to deliver but no one was in. No one tried to deliver. I WAS HOME AND SO WAS MY HUSBAND. MY DOGS WOULD HAVE BARKED. No card was left either. I needed the item urgently. I AM DISAPPOINTED TO SAY THE LEAST. I will always use an alternative from now on. I won't use Royal Mail as my first, second, third or fourth choice again. If I could have given No Star Rating, I would have done. CUSTOMER SERVICE TRAINING NEEDS INTRODUCING URGENT!
