We're deeeply sorry this time.
I didn't noticed that the tracking code had been changed.  I can't find the formal tracking code, but only found the one RA679701128CN. Thus I was thinking that one should be the only tracking code for this order.
Sorry again.
I suggest to provide you a coupon, cutting 5% off, this time. And we can refund your payment if this order will not arrive to you before Christmas.
OK?
