Skynet courier - worst service

Worst courier service. Sent a package on Thursday for overnight delivery to be delivered Friday or Sat morning latest, after I was told yes it'll definitely be delivered. Today, Monday, still not delivered. Spent whole day Saturday fighting with them about my package, apparently looking for the package the whole day, supposed to call me back before they close to let me know what's happening, nothing happened. Paid for overnight delivery but definitely didn't get overnight delivery.
