Car service mileage on vw system captured wrong

So I took my car for a service at VW Barons Pietermaritzburg, my car was going for a 45000km service, on their system they wrote 132000km and this has been affecting me whenever I wanna do claims, I called asking them to fix it but recently had to request for it again it still comes with the same mileage on the service history of my car,.. they are the worst to deal with. ***********, don’t bother going there, I’m also concerned if they did service my car because I don’t trust them anymore, they broke trust I had for them… they lost a customer … VW please assist to correct the mileage on the service history
