Self sustaining charitable centre and threat from rare person

This woman came to our clinic at 7 pm today ( I work from 10 am to 7 pm non stop) and she got check up for her 2 kids, husband and herself and got a certificate of fitness for her son who was checked from head to toe
Very few doctors issue fitness certificate because they play safe,incase anemic kid falls down , doctor may be called by the school and held responsible for the certificate.
I did issue a certificate because I fear none except higher powers
This kid had failed in a reputed school in class 2 and got admission to the school renowned in our area for taking failures,but for a price
She paid 500/- only for taking entire consultations for 4 and certificates
Her husband is threatening me about his connection with people and money back because I had charged more !!
My caller ID shows the number belonging to a scamster
Should I call the police for considering women doctors as soft Target?
Or should I let the woman live with a scamster and kids who keep failing due to blackmailing tactics towards teachers of reputed school and others whom she considers as vulnerable
God save women doctors from such women who call the shots through their husbands and themselves, showing off a team spirit of the duo.
I am sure that even police is aware of such activities resorted to by women along with their husbands
Pity you Seema Jain wife of Sanjay Jain claiming to be connected with R block RWA and resorting to blackmail, but my caller id show the number as spam and I wasn't even taking the spam call
Because for 500/- five hundred ruppees, you got 4 people checked by me with fitness certificate and I spent my precious half an hour
Witnessed and shocked by the drama created by you were a family of 5 from Hari Nagar, West Delhi and their presumption about South Delhi Women is that women here being educated and sophisticated !!
Nasty women are present everywhere, North South, East and West
No you can't change the mindsets of this West Delhi family about every South Delhi women as Rowdy !
I am not the one who has to teach lessons to likes of you
And I am going to work like a routine and as heavenly blessings.

This is the copy of message sent by Sanjay Jain, husband of Seema Jain, parents to kids relocated from a reputed school.

You are cheating people... asking for 100 then taking 500.... will surely take action against you.... you are a beggar and not a doctor ... I know everyone in R-Block association and will definitely file a complaint . more
