Fiat Egea Cross Alternator Issue - Factory Suggests Used Part Replacement

I took my Fiat Egea Cross to the service center because, for the past 10 days, a squeaking noise has been coming from the engine area while idling. After inspection, the service team stated that the alternator needed to be replaced and contacted the factory. However, the factory suggested installing a repaired, used, or refurbished alternator. My vehicle has only 20,000 km on it and is still under warranty until 2028. I absolutely do not accept the installation of a used part in such a new and warranted car. My license plate number is 06 DRZ 145. Although I contacted Fiat customer service, I have not yet received any response. I do not accept a used replacement part and demand that a brand-new, original alternator be installed under warranty. Otherwise, I will share my experience with others and will never choose the Fiat brand again. The related image is attached.
