Hi,
ZeroLemon has approved authorized resellers perform the after sale service, who will be responsible to replace/refund your verified purchasing items from them respectively.
Except for those authorized resellers we published on website, we won't be responsible for the item sold by any other unnamed seller, because we are sure that we did not supply the item for them, we cannot guarantee the quality and source for their items.
What our suggestion for you is to contact the seller directly to issue a replacement, or you can submit a claim on Amazon.
Please also feel free to report us by email to info@zerolemon.com if you find out they refuse to execute their duty.
To protect your purchase, please shop from our authorized resellers.
Your support and understanding would be highly appreciated!
Thank you.
