Delayed customer service

We bought a fridge from Loot in December. The fridge stopped working and since it is still under warranty we emailed, and after a couple of weeks, a lot of emails we finally got a technician to come and have a look. He immediately confirmed that it was in fact faulty, and that it will take only a few days to sort out replacement. After several more emails, and a week passing by, loot has failed to respond. We are without fridge/ freezer and don’t have the money to purchase A new one, and Because of lockdown we can’t get it sorted. This is unacceptable!
