Boat — Speaker service (it's been 30 days yet I dint got my product)

My product picked up on 7th July 21, and today 6th Aug 21, they took it for service its been one month yet I dint recived my product
After calling several times to customer care they sent tracking details, but in tracking details it is showing product estimated delivery is 10 July and it is showing product out of delivery on 12th July and 14th July . I don't know what to say,
For 10rs product companies giving good service, for being number sound systems in India, it is sad to say boAt service is worst at its best.
