Crossbeats — Orbit Infiniti / S4 MAX watch

I bought this product two months back. It worked exactly for a week then display gone. I have raised a compliant and they agreed to give replacement after two weeks. After some days when i followed up again they said model out of stock so will give you other model, that also i agreed. They asked me to pay additional amount of 100 for replacement and it's done. Now it's been two months and after multiple followup they are saying new model stock also not available. What a fraud and cheating company it is. They should not be encouraged to sell on-line. Worst and very rude customer care support. Simply lost 8000 by blindly going based on ads and design also thinking it's a Bangalore based Indian product. Wasted two months already not sure how to proceed further for replacement or refund
