PLEASE HELP is there any form of customer service here

[pg6]

Trying to get help as I am placing an order for a client and I seem to have a cap on how much I can order.
Anything over $175 says the order cannot be shipped to the selected address.
But if I take a couple items off and get it under $175 then no error message and the address is fine.
Will pay anyone who can help with this.

Go to your store -> settings -> Shipping and delivery

Check if there's any price conditions for shipping to that region, that could be causing the error.
