Lack of service trying to get a car serviced

Booked my Peugeot for a service. On a Saturday as it is the easiest day to arrange everything including having to pick it up. Then about 2 hours later I get phoned, and they say that they can't service my car as it should have been serviced in Feb according to their records as it is a year or 15 0000km. I only bought the car in September 2020 so they never updated the system when I bought it. Then arranged for my car to stay there until the Monday. So, Monday, I waited for them to ring me, as they say they will ring me. 9h00 I ring them as I haven't heard anything... they said they willl sort it out quickly and ring me back. An hour and a half later still nothing so I ring again. They are busy so they eventually ring back. Saying its been sorted. I ask them what time I need to be there to pick it, once again they will get back to me.. another hour later. I can come at 15h00. No sorry for the inconvienience caused, no offer of a courtesy vehicle to pick me up, as this was their mistake. Basically I needed to do damage control and rearrange my day due to their mistakes and slow service on getting back to me. Honestly, if I knew what I knew now.. I would have probably bought another car. Don't get me wrong, the Peugeot I drive is awesome.. but the after sales service... that was a very dissapointing experience.. And at the end of the day, a car will get you from A to B.. the service you receive is what makes the difference.
