The legal notice has been sent by Avtar Kaur, Harbhajan's mother, through his lawyers, Dewani Advocates & Consultants.
Harbhajan's lawyers, in the legal notice, have claimed that the commercial mocks the off-spinner, his family and the Sikh community.

In the Dhoni commercial, the Harbhajan look-alike works in a factory and gets slapped by his father for creating humongous iron balls in a tryst to 'make it large' at the ball-bearings workshop.
