I only want to send products to the warehouse with code RUH8.

I ship products to amazon warehouses from my home address in Riyadh. I send the parcels via Amazon contracted ATS cargo company. However, there has been a problem for a long time. Previously, I was sending products to the warehouse with code RUH8 in Riyadh. He no longer wants me to send it to this warehouse but to the amazon warehouse with the code JED3 in Jeddah.

However, unfortunately, it is not possible to send to the JED3 coded warehouse via ATS. I corresponded with customer services many times. They couldn't find a permanent solution. I want your help on this matter.

I want to send my products only to the amazon warehouse with code RUH8. Because ATS company only sends products to this warehouse.

Thanks for your help.
