Bad Service back and forth instructions

<p>I have a premier cheque account with FNB, I called last week to update personal details but everytime I call they can't help me or the call cuts.</p> <p>One agent informed me that I should should an e-mail with my payslip and new detail and they will update it.</p> <p>Today I get a response notifying me that I must call in to update my details.</p> <p>I am highly frustrated with FNB quick to call and sell you **** but cant provide a basic service.</p> <p> </p> <p> </p>
