I'm not saying it would fix it but Wi-Fi calling worked flawlessly on my 6 Plus so it's difficult for me sit here and experience this. My galaxy s5 last year had flawless Wi-Fi calling as well. This isn't a new feature, it's been around for years.
For your S5, was it running Lollipop or Kitkat?
If WIFI calling is a key feature for you, and your carrier (that's who you should be complaining to) isn't helping you out, then it's probably time to head to a new phone, as I doubt any sort of fix is going to happen quickly enough to help.
By the way, is it your home WIFI that you're connecting to? If so, and you have control over the router, have you looked at this WIFI thread (referenced from the Common Issues sticky): http://forums.androidcentral.com/lg-g4/538812-wifi-issues.html My own solution was to switch to using 2.4GHz instead of 5GHz, while others have had pretty good luck fixing their problem by switching 5GHz channels.
