I’m sorry to hear your buns are angry with you, I know it’s never fun when our bunnies are angry with us. When I had to give my buns medicine, they would eye me suspiciously and sometimes run away and I thought they would never get over it. The good news is they did get over it, and chances are yours will, too. It helped to keep a clear routine so that they knew what was happening when.
In terms of bonding, did you handle them in a different way than you usually do? Maybe the bonding sessions were too long? Too many on the same day? Generally with bonding, you want to start slowly, even if the buns know each other. Maybe start them at the same time for a while so that your buns know what to expect, and do really small sessions to begin with. Give them time and be patient. There’s a lot of good info on the bonding section of this forum. Check here: https://binkybunny.com/FORUM/tabid/54/aft/163352/Default.aspx . There’s really good info about bonding.
