Paytm.com — Incomplete product delivered

Address:

Bangalore, Karnataka

Order#[protected] for Rs 3955 was placed online on paytm.com for BSA Champ Star 12 inch Bicycle. Product delivered is without the front mudguard and carrier. Matter was taken up thru Emails with Paytm & they were requested to despatch the missing parts. Though accepting that partial product was delivered, resolution given by them is refund of Rs 200 to my Pattm Account. This is very unfair. Can I ask my child to use a new product that is deficient? Now Paytm is selling online - Mahindra motor bikes. Will they also be giving refunds for incomplete bikes delivered, ie, say without rear wheel, engine etc. Paytm is again requested to ship the missing parts.
