Lenovo — back to college offer

I have purchased lenovo laptop in june 28th, 2019 under lenovo btc offer.
In which i have paid 1999 rs extra for additional 3 years of warranty and 1 tb hard disk drive at 1499 rs.

I have received 3 years extended warranty certificate but lenovo has not delivered 1 tb lenovo hard disk drive yet.

In last mail they apologize for late service and promised me to deliver hard disk drive after that they just stop responding my mail.

I request you to take necessary action on this.

Ticket no: btc-286617

Thanks & regards,
Hassan alam
