Bosch Fridge/Freezer - Technology at its worst!

I have had a Bosch fridge/freezer for 18 months. Bought it in October 2019. It has now broken down for the 3rd time. This is unacceptable for a fridge that I paid R 16 000 for. I would like it exchanged for a new one or my money back. This is absolutely unacceptable. And each time everything in the fridge is spoilt which no one compensates me for. Disgusting service on the part of Bosch. I demand that this be escalated to top management. Thank you
