Voice chat still not working

That post sums up my issue. Vc works for 1 match then doesnt join again. If i restart OW it works for 1 more match. I called support and the guy was a total a hole. Ive gone through hundreds of fixes to no avail. Its not my end as i once thought. Yes i use a tether from my phone BUT its a solid connection and i do just fine. So my question is there a fix or is it another blizzard problem ill never see resolved?

Voice chat requires a lot of bandwidth to function. In combination with game data, your mobile connection is likely being overloaded.

From the staff:

The only troubleshooting I can offer is to use a supported connection type.

Same bs i was told by the support agent BUT its not overloaded. If you guys wanna send me 500 bucks i can get better lines at my house. Currently a 1 mb connection is all thats available. And its spotty. But my phones almost 20mb/s
