Hyundai Veloster back shocks need replacment but only one approved to be replaced but both must be replaced!!!!!!!

Good evening Team,

I do have an Urgent Complain that need attention from Liquid Capital Complains manager Department..

My Hyundai Veloster White in Colour , Reg Number: JFZ 114 NW , Engine Number: G4FDEU576246, Vin Number: KMHTC61DLEU196710 70850KM do have an problem with the shocks and i do have an maintenance and extended service plan on this vehicle both the back shocks need to be replaced as i can feel the back shock need to be replaced as the vehichle are driving very bumpy at the back , i did contact Hyundai Brits Service Department Suzie and she asked me to go and do a Shock test and the test show the following Left rear as in the bottom yellow near the red mark 0.23 and the Right side Rear is showing 0.19 in the red mark ..... I did send all documents and information to the service department at Hyundai Brits and they informed in an an hour time that my Maintenance Plan Liquid Capital are only going to replace the one shock that in the red. And im not really happy with the feedback proved as both shocks need's replacement and im leaving on holiday 08th Feb and cant drive with the vehicle like this from Brits towards Capetown and back like this.. Will you look into this matter as Urgent and let me know whats going on as this is unacceptable the way Liquid Capital are handling this matter as they can see on the shock test both shocks must be replaced..
