Bad service from Vodacom

A few months ago I purchased (still paying for it) a Samsung S10. Very recently a black dot appeared on the lower end of my screen and it seems to be the LCD. I have taken my phone to both the Samsung centre in Nandi drive and they have refused to fix the screen aswell as vodacom in musgrave. 3 weeks ago a purple line has appeared on my screen and my phone is keeps going black(the screen) and making it almost impossible to use the device. I went back to vodacom in musgrave and they referred me to the Vodacom Repair centre on Old Fort Road. The technician (Salliem) was extremely rude and not helpful at all. He stated I have dented or dropped my phone and wont fix it under warranty. I did show him my device that there is no crack on my screen but simply a scratch (which could have happened anywhere,even the keys in my pocket) but he said its physical damage by me. It is extremely disappointing that I am paying alot of money towards the phone every month and they refuse to assist and want me to pay R4500 to repair the phone.

Upsetting service from vodacom as I've been a customer for many years prior to this. Once my contract is done in a year I will definitely be moving to a different service provider and informing all those that I know to move over aswell incase they have the same issue as they will not be helped.
