A Natwest customer was left appalled after a Business Manager accidentally left him a three-minute voicemail message mocking his financial situation and calling him a KNOB. Nathan Eames, 39, received a call from a business team manager to discuss the feedback that he'd recently left on a customer service survey. But the call went straight to answerphone and the business manager left a message requesting the customer to call back. After thinking she had hung up she was heard joking with colleagues about Nathan's application for a loan and was even heard calling him a "knob".
