Clearing Backlog By Rejecting Application OR Xenophobia

A wife of friend of ours app**** for PR using her hubby's PR. And a lady from DHA phoned to verify/confirm their marriage. The lady didn't say where she is phoning from, or who she is, upon asking her where is she was calling from, she became insolent. My friends explained to her, they get a lot of spam calls people trying to sell them insurance [for eg]. Finally she decided to say who she is, and in the conversation she pointed out she could fail their application because she could "not" verify that they were together. And then three to four weeks after, the wife's application was rejected despite the fact she submitted all the supporting documents. Luckily our friends recorded the entire conversation, and now they are mooting the idea going public with the voice recording, and want to take the DHA to the Public Protector
