Appalling, Non-Existent Customer Service

<p>As an existing customer, upgrading her mobile contract I did not expect to wait 4 days to hear if my application was successful. </p> <p>I also did not expect to phone the Cresta branch and have zero reply.</p> <p>I was promised an email and a call confirming the contract.</p> <p>I wait with baited breath.</p> <p> </p> <p> </p>
