Finding
Figures show that we received 300 complaint emails in January,which is the normal level.However,the number increased rapidly to 540 in February due to the computer virus breakout.But it cannot be the problem after we upgraded our antivirus software.In view of the reasons for complaints,the main concern is delivering speed.More than a half of our clients were unsatisfied with our logistics service.As for quality,a lot of complaints have been received because of the signal error of the toys cars.In addition,the computer virus accident has been solved and we have sent all the incorrect packages in to right address in March.
Conclusion
The logistics has been the bottle neck of our firm and an investigation of the toy cars should be done.
