Inside job - unable to provide a ref for the call

Called Discovery to report an unknown transaction.<br> <br> Mr Moses Koreloso decides it needs to be referred to the merchant.<br> <br> Fair enough, he doesn't know me and can't take my word that I'm unaware and didn't authorize the transaction.<br> <br> What I can't understand is why I'm supposed to hang up and take his word that the query will be processed when he cannot give me a reference number for the call ?<br> <br> That rings massive alarm bells.<br> <br> FWIW - I'm still on hold 42 minutes later and I haven't heard from \Mr"Koreloso for over 30 minutes. <br> <br> I have my mobile on charge and have all day.
