2nd Time Buyer, Not Happy

I Bought a BMW X3 from We Buy Cars. The Car Began overheating in August, discovered that the Top radiator hose had been bonded to the radiator with a Sealant/adhesive and coolant had been leaking. purchased new top radiator hose and had it fitted and now the Vehicle needs a PCV Valve replacement. took delivery of the vehicle on the 25th of July 2022 and these were noted in the Dekra Report and the vehicle had been through to the Recon Centre so the vehicle Passed the inspection with the poor workmanship on the Top Radiator Pipe? I Logged a Complaint and was advised to Take the Vehicle to an RMI Repair Centre which i did and the Innovation Group warranty does not cover the Repair and i have provided the estimate of costs as requested to the customer care Agent and Still No Response
