Hi Following the thread above, would the same theory apply to own personal belongings. I had left my own headphones in Lux and got my friend to courier back (declared as a personal belonging evidence by Argos invoice 2 years ago under my name). Courier company invoiced after delivered (not advise before), charged duty and taxes that was nearly half of original cost of my own personal headphones purchase price. Can I challenge the courier company to revise on returned personal own belongings?
