We say that they are toing and froing.

我们说他们来来回回。

Come on, we've been toing and froing on this all week let's just make a call.

来吧，我们这整周都，让我们直接打个电话吧。

But unlike toing and froing where you're switching between different opinions or different ideas well this expression is more about actions and decisions so when you keep changing the plan.

但是和反反复复，意思是你正的想法之间切换，这个表达更多地是关于行动和决定，因此就是当你一直改变计划的时候。

It wasn't just the time, although the endless hours spent at hospital, the time spent toing and froing in the car, the meetings – oh God, the meetings – took up so much of it.

仅仅是时间， 尽管医院度过的无休止的时间，车里来回走动的时间， 会议——哦天哪， 会议——占据了很多时间。
