"Pah! I worked with someone who went to the wrong African COUNTRY on a support call."
Bollocks! You beat me! We had our south west engineer go to a call in Poole, Dorset, pre-sat-nav and smartphone era. He rang back after a 2 hour drive saying he can't find the street. He'd even asked around and none of the locals knew it either. Bloody call centre had got confused and should have sent one of the northern engineers to Poole, near Otley in North Yorks.
