BSA Hercules — Defective cycle

On 21/03/2021, I had purchased a BSA Hercules cycle having no. STEET CAT PRO 26T.
I got a defective product.
It's brake, flywheel, pedal, chain is not working well. The chain had broked many times and sound is coming from every part of the cycle.

Kindly, resolve my problem as soon as possible.

Thanks
