She may have proofs but it's not like she's in a court presenting witnesses, it's all about words and who would believe her. also let's not forget that in the earlier chapters she was completely under the control of bella's father so even if she said she has proof all of this proofs could easily be nullified by her uncle

Oh that s how she impersonated Harriet
Sknce the beginning I was like they look nothing alike how can they mistook Bella for Harriet ?
