Lenovo — About the power cord in the box

Dear Customer care

As a loyal customer of Lenevo, I would like to bring to your kind notice that I bought a Lenevo Laptop on Jan 30 . and the box shows the following contents

1.Laptop computer system
2. Adapter
3. Manual
4. Power cord

But unfortunately the adapter is missing from the box. Instead it has a charger of a mobile phone. My model no is 81WB01E6IN. My invoice no is TA[protected]

Please look into the matter.

Regards
Prof. D.S Ray
