Regretting getting Samsung S8

A few weeks ago I dropped my Samsung S8 and as a result my screen cracked. I took my phone to Samsung repair centre in Constantia Kloof Roodepoort. Where I got a damage report (which I had to pay for) I submitted a claim to my insurance company which was approved and the money to get screen repaired paid into my account.

BUT when I wanted to take my phone back to Samsung Constantia Kloof they were closed with only the call centre number on the door. I then phoned the number provided and from there I have had to success in getting my screen repaired. They keep on giving me numbers for places where I can take my phone but the problem is that these companies charge different amounts to what Samsung originally quoted me - more than R1000 more!!! As a result of Samsung closing their branch I am now stuck with a screen that is cracked and cant get it repaired at any of the other companies as they charge more.

When I phone Samsung customer service to speak to a manager all I get told is that the manager is going to say the same thing "these companies are independently owned and they charge their own prices" So must I now just pay the R1000 (which insurance is not covering because the paid out on the original quote FROM SAMSUNG)
