iBall — BT4 Head set not working

I have purchase head set which is not working. Due to lock down i am not able to go to service center i have given Vashi office as on[protected] for repair purpose but they says that it was rejected by company. i have purchase in Aug-19 and its have one year warranty. But due to lock down i am not able to go to service center. Product was stop working from April-20 but due to Covide -19 not able to go and service center are also close. so i am requesting to either repair or replacement the product. Other wise i need to go the consumer court for this.
