mi5s plus boot problem

Hi there
Thank you for your email.
Sorry about the problems, in this case, could you please return this defective item to us for replacement? We will send you new one after we received it.
About the shipping, please pay attention to the following:
1. Send back the item WITH the original box,cables & charger.
2. Please send item back to us through local post office instead of express service like DHL,UPS,TNT,FEDEX... as it likely will incur import taxes when it reaches customs and it may also be delayed during the customs clearance process. If we can't receive the item we can't arrange the replacement or repairing.
3. Please print the attached authorized paper out and fill in the information ( ORDER NUMBER & the problems),
4. Pack the item carefully with bubble and make sure it won’t be damaged during the shipping, declare the package as "Gift " and low values (lower than 30 usd ) if you can.
5. Inform us the tracking numbers after you send and we will inform you when it arrives.
If the shipping fee with tracking number more than 20$, could you please send it back without the tracking number which can save the cost?

Thanks for your kind understanding and cooperation.
Sincerely,
Una
