Sansui India — Complaint against technicians n customer care department

Have bought sansui 6.5 kg semi automatic washing machine one month back, machine giving some sound while operating. Have registered complaint with customer support team still no call no visit from technician 3 days passed. After frequently calling customer care no valid update they speak their recorded statements only. Past three days my mother washing clothes by hand she is old, inspite of telling all this to customer care they are not taking any immediate steps to check why technician not calling n visit. Sansui is very renowned in market y after sales service is not proper. Please help me as i m unable to use machine unless technician visits. My area north goa .My service request number GASW[protected]
