Byju's — Breach of service promised

Hi

We have been promised while buying the service that if there any issue with device the device will be replaced for the life time of the contract ( 5 years)

I paid more than 76000 for the same and now that there is some issue with device they are mentioning that they won't replace the device and we should get it repaired.

Also I mentioned them that quality of there content is not same as what they demoed and now these issues are coming as well on which the staff from BYJU's was very rude and said we can do whatever we want to.. really this the quality of Indian businesses?

The above mentioned incident took place at 21-Aug-2020.
I am very unhappy and would like to get refunded for the remaining of the period and if they don't do that then may be I will spend more but will make sure will get proper case against them in court of law (already in talk with my lawyer).

Regards,
Ritesh
