Disgusting service from Wumdrop regarding delivery

I expected my delivery from Game Eastgate to be delivered by Wumdrop, on Friday 28th August, according to the tracking information provided by Wumdrop. Driver had a puncture could not deliver, but logged it as delivered and signed for by someone, who was not me and then kept the item with him overnight at his place of residence. Apparently he then returned the item to Game Eastgate on Saturday the 29th, and I have confirmed this with Game Eastgate. But when I called Wumdrop this morning, the call agent says it's logged as having been returned on Friday the 28th. This is impossible as the driver admitted to me to that he had my item with him overnight from Friday to Saturday.

I'm not sure if this is the standard way of treating customers, through saying that something is delivered when it hasn't been and lying about dates when items are returned back to the store as it couldn't be delivered. After checking this morning ont he wumdrop tracking information, it now states that it has been delivered to me and I have apparently signed for it, when I clearly haven't and it is currently sitting at Eastage store. Is this the way that a customer is treated and **** to. This is disgusting.
