Boat — earphones replacement not received

Hey, i'm amit. I sent my boat rockerz 225 for replacement on 2nd june 2020 and it's been almost 20 days since i last got an update from them. I've tried emailing them but it shows their inbox is full. I tried contacting the customer care but the call just automatically disconnects after i choose to talk to their executive. My ticket no. Is 1126163. I'd be so grateful if i can get help from here.
Thankyou.
