Reliance Jio Infocomm — removal of photo of earlier person (lady

My name is prakash rasania. Recently, i purchased a reliance jio card no. [protected]. Now i am rightful owner of this number. However, in whattsapp application, the dp profile shown is that of earlier owner of this number. I am a male & it is embarassing when my dp profile is shown as some lady. You are kindly requested to remove her photo from dp. I have already lodged phone telephonically over toll free number & i was given assurance that within 24 hours, it shall be removed, but even after 5 days, it is not removed. Please expedite this complaint.
