Vodacom disappointment

Good Day. I have contracts with Vodacom and the latest was in December 2025. Oppo A5 m. The phone started heating quite often. My son kept it aside and went to bed. The next morning the cell was warped due to how hot it got. I went to a Vodacom store and enquired and the sales reps advised to go to the store that I took the contract from they should assist as she has the same cell and it over heats. The screen did have slight scratches and their technician states it looks like it was dropped so there's nothing they can do to assist. I cannot afford to have the cell insured. It's still on a contract they should of assisted with sorting the heating and the cover.. Not the screen as there are fine scratches on. The quote was R3800
