Russia’s postal service has been made to compensate a woman who shipped an iPhone 5, only to find it had been replaced by a handful of stones on the receiving end.

      The mobile phone was sent from Moscow to the southern city of Rostov-on-Don in July using Russian Post’s express mail service, according to the state-run Public Chamber rights watchdog.

      The sender, whose name was withheld, spent three months fighting to get 30,000 rubles ($940) in compensation. The money was paid last Monday after the Public Chamber intervened. Russian Post is investigating the incident, the watchdog said.

      Russian Post, a state-owned monopoly, was ranked among the world’s worst postal services last year in a study whose authors included experts from Harvard and the Paris-based EDHEC Business School.
