New Fridge but needs repairs constantly en refusal to exchange for a new unit

We bought a Defy Fridge from Hirch Montana and Hirsch tried there best to get the Fridge exchanged after 2 repairs in less then a month. Fridge is not even 5 months old. Defy just want to keep on fixing it. First the rubber then rhe bottom door now then want to fix the upper door then the plastic outside. So what did I pay for? A SECOND HAND FRIDGE THAT NEEDS CONSTANT REPAIRS!!!!! RHIRD REPAIR NOTICE: The appointment for ***5 has been rescheduled to 19.05.2026. Please expect a call from *** AS ELECTRONICS REPAIRS to confirm the appointment
