Earbuds not working

I received my parcel i.e., audionic earbuds today under model name-AIRBUD550, and they aren't working at all, i even faced a problem with the connection too. I want a refund or at least an exchange with the new one. I also would like to mention that i will appreciate if i check the exchanged airpods while recieving so that i might not face this same issue again. Thankyou
