I think you can challenge it, they once sent me the detailed documents with the cost before asking whether to clear it behalf of me, Since I am not an expert in duties and anything under 10k isn't worth fighting for I didn't go to check/argue. But I didn't see any issues there machan.
this is exactly what happens to me 2 years ago guys, I had a guestimate about the tax about based on the hs codes for items i ordered (about 40-45%), and asked presto guys to handle custom stuff. but once they handed me the items and the documents, tax rate is almost 75% or 80% basically double the cost at the end.Nope they do not provide the original tax receipt from the customs
Plus Fedex can print whatever tax amount they wish us to see
since that day i'm bit scared about presto's custom handling and documentation. i though next time i order I'll go by myself to release the items from customs instead of asking from presto.
