Hawkeye complaint dismissed. According to logs he was fighting multiple suspects including Surge + at 0:12 you can see that he was climbing over the fence to run towards both of you, so he was clearly not teaming.
c@rtel complaint dismissed too, logs have shown that he was attacking Surge prior to your kill. Question why he didn't chase him further after killing you is open, but I'm gonna assume he was under-equipped for that, considering how people feel about attacking "skilled" players, that's why he immediately went to Ammunation.
Clover is dismissed as well, same case as c@rtel's. He was extremly low and had fought another suspect before targeting you. If I were him, even with a backup, I would think either to retreat and refill or attack Surge.
To sum up, I can only assume that they didn't go for Surge because they were unsure about taking him down without dying, even if it was 1v3 or 1v2. I wish I could saw another recording after you died from different pov, but that's unfortunately isn't going to happen...
Dissmised.
