for some weird reason, replacing your s20+'s display is going to cost less than repairing my s10+ display 😕
try to negotiate with them, push them to find a middle ground with repair cost.
Also, try to use covid as an excuse ;) they extended warranties for a month during covid days, you can make an excuse for 2.
This is why I bought S10+ after testing S20+ at demo stands. Everyone thought I was crazy to skip the latest flagship. Exynos 990 really turns hot even with basic usage. Phones using Exynos 990 are bound to have random errors with time.
