I'm at a complete impasse

Dude. Every. Fn. Scorecard. EVERY SINGLE ONE I have people giving me bad feedback over shit that I didn't do!!!!! I literally can't get my guaranteed 40 because these people are fn STRAIGHT UP LYING. I had 4 dnrs the past 2 weeks and I know for a fact I didn't deliver to the wrong address. Had one person say I was unprofessional??? I haven't done anything in front of people or doorbell cameras, nor have I thrown packages or anything. Like what the actual hell. Help! What do I do??
