Huawei cellphone

I purchased my Huawei NOVA9 cellphone approximately 7 months ago.

About a week ago I noticed that the cellphone is badly bent and there is a huge gap between the screen and the shell of the phone, I went to Vodacom in Richards Bay where I had purchased the phone, I asked the tech guy to check the phone for me and he told me that this is a battery problem, it could either be from over charging or a factory fault, he then accused me of over charging the phone and then told me he would be testing the phone, only to find out that the phone was not over charged. Then he asked me how long I've had the phone which I then responded with saying I've had the phone for 7 months, he then said well unfortunately the battery warranty is only valid for 6 months, he said the phone can be sent away at my own expense for maybe up to a month. All the info on the phone would be lost. I need the phone as most of my school projects as well as homework etc...… is on the phone, he politely rep**** that it is my problem and he cant help me unless I pay for the repairs or at least a deposit there of. He said the cost of repairs would roughly be about R2000.00 which I honestly feel is a ******* as I paid cash ( R11 000.00 ) when I purchased my cellphone.

I am honestly very disappointed in both Vodacom and Huawei with the service I have received.
