Charu's mysterious caller/harasser is Rachna...

The girl calling Charu has got to be Rachna changing up her voice a bit. If you listen closely to the voice in today's episode it sounds like Rachna's. Also, they show the figure of the girl calling Charu and even though the silhouette is hidden in darkness, you can make out the hair and it looks like Rachna. Since Rachna is in on Mayank's plan to decieve and expose Charu, it makes sense that the caller would be Rachna. The only think I can't explain is how she would've gotten a photo of Charu burning her saree but that is probably just an oversight on the CVs part...I mean if Rachna or anyone else had snapped the pic or known of its existence, Mayank and his family could've been spared the whole ordeal of prison. We know Rachna is changing and becoming bolder now so she wouldn't hesitate to call Charu especially if Mayank asked her to. It can't be Seema, Sangeeta, Gunjan, or Shail because they were all in the room when Charu answered the landline. The only female missing was Rachna.

Yep...confirmed! Just saw latter part of eppy and Rachna was shown as the caller! I got so excited that I posted earlier before watching the whole eppy lol. 😆
