Bosch - A disgrace

I bought a Bosch Fridge/Freezer in October 2019. The fridge fan broke in early 2020. Waited a month for a new part from Germany. Now a week ago it broke again. This is twice in 17 months. I have complained to the call centre for a week - every day. I asked for someone to call me and each day am promised a call. I want this fridge replaced. But am getting no service out of Bosch. In the meantime I have had no fridge for a week. This is unacceptable. I paid R 16 000 for this fridge which has broken down twice already. And no-one gets back to me. An absolute disgrace
