Poor quality fridge and after-sales service from Hisense

I have been trying to replace a glass shelf from my double door fridge that I bought from Hisense for months now. The shelf literally shattered the one day when my wife opened the fridge door - and there was glass everywhere. Despite the obvious quality issue, I've been trying to replace the shelf and have had very little joy from Hisense and their spares department. Specifically Caroline Moloisi who contacted me on email once and has since been ignoring my follow up mails. Poor quality fridge and subsequent poor quality after-sakles service.
