Flipkart — Wrong Item received (Rs 4500 cheaper)

Address:

Flipkart India Private Limited registered address is Vaishnavi Summit, Ground Floor, 7th Main, 80 Feet Road, 3rd Block, Koramangala Industrial Layout,

I ordered a rowing machine costing 18, 999 of HRX RM500 on 29th Nov. Instead, I received HRX Ignite on 3rd. Immediately raised a complaint with flipkart on 4th Dec.. They asked for images, I sent it. Another team asked for Images, I sent them again in a .pdf document (they do accept .pdf within 2mb. I wanted to attach as many images as possible and hence used .pdf.). I kept calling them daily and was assured the issue will be resolve by 16th Dec.

Each customer agent seemed to have understood the proble orally. But, the mail/messages I receiver were:
1.Unable to reach me on 7th DEc (I had network connectivity.I requested call back and they called immediately. Of course, it was a different person who seemed to have understood the issue and assured to solve it.)
2.On 8th they wanted consent to file FIR for filing 'Missing Items'. I did not give consent as the issue was 'wrong item sent' and not 'missing items.
3. I called again on 8th dec and was adviced to add photos. After the call, my issue was changed to RESOLVED. I re-opened the issue.
4.Today, 11th Dec, they are mailing that they have rejected for not giving consent for FIR.
