Oh, that makes it awkward, i kinda assumed you were ost with all the talk about Elefant and whatnot
I'd probably have to rewatch the replay from your perspective to get a full picture, but here's a shorter list
1. You had your JPIV go right past a near dead churchill without firing a single shot (I bet it was on move command), so yeah, small micro mistake.
2. Your opponents were coordinated, employing avariety of units, meanwhile your teammate was losing stuff left and right, and had NO AT for almost the entire game... You don't expect to 1v2 allies do you?
3. I'm sorry that you just can't play with what you want and win, but thats how life works, it's called "meta", get used to it.
4. There are plenty of other suggested solutions to your problem, like Pak43, HEAT shells etc. or not having a teammate that literally throws away 700 fuel.
