Mivi — Mivi f30

As I submit my problem related my duo pods to claim warranty. I received the mail Mivi said we will pick your product and repair it there is no response after it. No one picked my product to repair it. And now my f40 also have such issues like right earbud give less sound then left earbud, but if my f30 not fixed by Mivi then what I expect you repair my f40
