Disgusting service from Huawei South Africa

I have a P9 lite device which indicated on the Hi-Suite desktop manager that there was a software update available. I trusted this information as it is the official Huawei desktop manager and Huawei software. After installing this update, my phone became un-useable. The version loaded was NRD90M-Test Keys. I need to say again that before the update, the device was working perfectly.

I took the device into the service centre in Melrose Arch in Johannesburg. The staff there were very unhelpful and quite disinterested in my problem. They said that I must book the phone in for repairs and as it is out of warranty, I will need to pay for the repair I received a quotation that is 2/3 the cost of purchasing a brand new device.

If I had damaged the phone in any way, I can accept that I would need to pay… however, nothing I did was wrong. It was Huawei software via the Huawei desktop manager.

I find this sort of service and support totally unacceptable
