OPPO / Vodaco Disaster Phone!!!

Please do not get an OPPO. My Oppo is not even a year old and started eating the battery power within 6hrs to 1%. I went to Vodacom and had to pay for a Firmware update at Vodacom Cycad Polokwane. I got the phone at Vodacom Mall of The North Polokwane. I was told that I do not have to buy a screen protector as it is already fitted with one. The first time it fell the screen cracked. I went back and was told that they never told me that it has a screen protector on. The phone has to go to Gauteng for 7 working days. This is inconvenient, as I have a sales app on the phone for work, so I cannot send it in. The cost of the screen is R2500. The phone costs R5500. The phone is not suitable for my sales app as it goes out of the app when trying to select a product option. When I took this contract at Vodacom I explicitly specified that this is what I would be using the phone for. Why is there no service back-up in Polokwane for Oppo? OPPO complaints are so slow to react to complaints!! They are pathetic!!!
