WeBuyCars - aftersales bad - don't believe the Dekra report

Bought a vehicle with a Dekra PLATINUM status - all aspects of the car were marked very good on the report. The radio did not work but the message that was given "just take the car to the dealership they'll punch in the radio code to get it going" - radio was totally locked and had to be replaced. 2 Days later the engine light came on. 3 days later I took the car to have its suspension checked because of the harsh ride - all shocks worn out, control arms faulty. HOW CAN YOU GET A PLATINUM STATUS ON A CAR WITH ALL THESE FAULTS WEBUYCARS???? When reported to WBC - their aftersales service sucks - been 18 days since I reported all of these issues - and none is fixed. Try their "customer care" - never available, will always call back, which never happens. Even emails that is sent is not being answered. My advise? AVOID this dealership unless they start looking better after their customers and not chase selling cars all the time
