Complaint about a (Renault Triber 2020)

on 25 Sept 2020, myself and my wife bought a NEW Renault Triber 2020. On 27 Oct 2020 my wife heard a funny sound from it squeaking badly, we called a tow-truck to send to Renault Paarden Eiland CT where we bought it. It was discovered that an engine mounting was completely broken. at the time the vehicle had 1000km on a clock. It also damaged exhaust manifold as a result of a funny sound, the vehicle also had an oil underneath, we couldn't see where it came from. We were told about a factory fault. After a week a workshop manager loaned us a Renault Kwid. The managers are running away and making excuses of meeting. We are paying installment, insurance for a broken vehicle. Today, the 18 Nov 2020 we received a call from Renault that we must bring it back the vehicle. We do not know what to do? Bertie (manager) promised to get back to us up until today.
