REPAIRS

I have been your loyal customer for 5 years not one single issue with you guys. I got an iphone 7 plus in January 2017 bought a cover for it and had a tampered glass on it from day 1. Last week i noticed my iphone 7 plus getting very hot so from observation of it i saw it was already bent on the top of the phone. I took it in to Randfontein Vodacom Branch in which the lady inspected it and said there is not one drop mark scratch or any kind of malicious wear on the phone except the bending of the phone on top, the phone went to Fourways then to advanced repair centre in which i got a message today saying need to accept a quote yes or no. When phoning to the call centre they gave me an option of getting a new phone with paying in R 8000, in which i responded why is this not under my warranty as this phone is bent on the shell. I then got to speak to a lady by the name of Melania in which she stated that i could of sat on my phone or bent my phone intentionally for it to bend like that, i then asked to be put through to a supervisor in which i spoke to Thato he then insisted bent phones from apple does not fall under warranty and that he has never heard of anyone complaining about a bent iphone, if anyone from vodacom just googles bent iphone 7 plus phones there are thousands of complaints even on APPLE site itself. So my question to you Vodacom is please prove to me that i bent this phone? I wanna see this assesment done so that i can know that i sat, or bent this steel allumnium phone with my hands then i can agree to pay for this phone if you cannot prove that i dropped or sat or bent this phone then this phone should fall under waranty. If this is not the case and you guys feel that i did this and then its betteerr you guys keep the phone refund me my handset installment that i have paid so far and void my contract as you guys are not fufilling you warranty status on this phone.
