My package was held in customs and I completed the declration when i was contacted by them to have it done. This was back in 9/6. How long will it take to be inspected?

The tracking update says waiting for customer fees payment, but my receiver in China cannot pay or doesn't have a link to pay. Can I add their phone number to the order so they can pay the taxes? They do not have any information to pay the taxes. How can we get this sorted?

Greetings! I have two packages coming from Japan to China (RX110103118JP and RX110610914JP) and now they are both in Shenzhen customs for more than a month. I am the receiver as my name is on the airway bill, but the address on the bill is from my P.O. Box in China. I contacted the seller, the carrier and my PO box and none of them can help me. My question is, I live in Chile, can I pay taxes or make a declaration from a distance so that my packages are delivered from customs? Or what other option can I have? The salesperson in the Japan store gave me this contact number 0755-2675-6110, I don't know how to call from where I am because I don't speak Chinese. Please, I beg your help and advice because I am alone in this.
