Welcome to the community!
With what phone are you trying to use an eSIM? I'm not sure why they would be trying to discourage you from transferring from SIM to eSIM. Is it possible eSIM for your phone isn't supported?
As mentioned above most retail stores can provide the eSIM QR codes (except Best Buy) (see here). Do you have one of the devices listed in that link?
Hope this helps 😀
