Boult Audio — Speaker is not working

Address:

NHS 10/113, Kumardihi B colliery A B pit

I purchased a Boult audio x1 from Flipkart but just use of 2-3 weeks i faced some problem but when i contact customer care they said to courier the product for repairing but they don't know how much charges are taking for courier a product 150+Rs i am not rich how i will courier my product? Other companies like Boat, Mivi & many other companies they send pick up for customer. They don't say to courier the product but Boult company is very bad they said to courier. Next time i will not purchase any product from Boult because they don't help in service time
