Bad service

I did my contract upgrade on the 15/05/2019 at a Telekom store in Gateway shopping centre. I upgraded from Samsung s8 to S10. Thursday night I started experiencing problems with my NEW S10, the phone froze when accessing some of my apps. It did the same thing Friday morning. I then went to Telekom and I advised them of the issue, they said the problem was with my screen protector and that there is nothing wrong with my phone. I told them I tested the phone without the screen protector however it did the same thing. I was told they can't help me because there is nothing wrong with it.

When I shared my same experience with them that when I upgraded to S8 my phone did the same thing and I thought it was because it was still updating software and I ended up not having a phone for almost 2 months as it was sent for repairs. I told them I wanted to change the brand but they insisted that there's nothing wrong with the device.

Because I was not willing to take it back and have issues, I ended up canceling my contract and taking a new one as I need the phone. As it is im sitting with S10 waiting for someone to come and collect it from me. So now I'm going to be paying loads of money this because of Telekom. I have 3 contract with Telekom and every time I upgrade I must have an unpleasant experience.

The contract clearly states that should you have issues with the device within 7 days of purchase you must take it back. Now I'm confused you take it to be told that it's working fine and you must just deal with whatever issues.
