C30 injection nozzle defective after 9700km, no culant!

Dear people, it’s to cry!! I stayed on the AB last week, engine stuttered, no more gas, just saved me from the left on the side stripes, the ADAC then towed me over the Volvo Assistance. The Volvo dealer attested a broken injection nozzle, 890.- Tacken, no culant, because the car is 3 years and 4 months old. Neither the workshop to which he was towed, nor their sister workshop where I bought it, were also only to a pro zent ready to trade with you! I’m totally appalled about how to be treated as a customer at Volvo!! Unfortunately I didn’t get further through the hotline in Cologne, I hung in the waiting loop in 3 days about 6 hours!! I have already filled out the form provided there, only none of Volvo’s messages By the way, it’s the third time that I stayed on the AB, once wg soot particle filter and once wg no one knew… the car is I was always waiting for Volvo, the last one was 8 weeks ago…. So I picked up the car again today, paid and that was it. That was my first new car, my first (and last!) Volvo. I sell it as soon as possible again! (You are welcome to ask!). I can’t do anything for driving only a little by car… I was told that I should drive more, then a part of it wouldn’t break either, isn’t it outrageous?? I’ve already driven many car brands , Mercedes, Alfa, Lancia, BMW, but that’s never happened to me before. Have you had similar experiences? Can I do anything afterwards? I’m soooo stinking mad
