In my experience Royal Mail are incompetent, and untrustworthy, they are an extremely unreliable courier, they consistently do not deliver by the deadlines they themselves set; I have experienced their drivers telling lies about items being delivered, stating the item has been delivered when it hasn't, only for it to be delivered the day after it should have been! I don't usually order items that are being delivered by Royal Mail, as their service is really appalling, but as I recently wanted a difficult to find item a company was selling through Amazon marketplace I had no choice. According to tracking the item was collected by Royal Mail on 01.12.23, it was due for delivery on 13.12.23 (why it takes two weeks between collecting the item and delivery who knows!). As the item is expensive I waited in all day, taking time off of work, all day the tracking information was stating the item would be with me by 8pm; lo and behold, at 8,05pm the tracking information changed, now stating the item will be delivered by 18.12.23! Utterly appalling and inept standard of service.
