Used their same day courier service. Driver arrives on time to collect. Item handed to them immediately at door. CitySprint own systems show arrival at 10:36 and collection at 10:38. Driver arrives at delivery at 12:44 and items shown delivered at 12:48 - again times are from CitySprint own tracking systems. Surprised to find extra charge on charge 2 days later for £7 for "waiting time". Driver has claimed for 6 minutes waiting time on collection and 8 minutes waiting time at delivery, despite true "waiting" time being far less. The 14 minutes waiting charged puts waiting time over a threshold (i believe 11 minutes) so all waiting time is then charged - hence the additional fee. Raised concerns of possible fraud with their customer team and got a generic "we're refunding you" email. No concern at all that driver was able to charge for additional non-existent waiting time, or that billing systems permitted them to do so when official timings showed otherwise. To clarify i have no issues with there being charges for excess waiting time. My problem here is that the driver falsely claimed waiting time that didn't exist, and the company don't seem to care. Delivery itself was fine but serious concerns regarding billing practices. Would suggest do not use them, but if you do be extra vigilent for charges after the event and make sure to make note of all timings and take screenshots of all tracking events from their tracking page. If you've previously been charged for waiting time then go into the app and check all the job timings to make sure you haven't also been charged falsely.
