Customer Care is proving to be shocking

<p>I am now really upset - I have been trying to cancel my account since the 25th of last month and no-one is able to assist me correctly. I asked to go onto pay as you go so I could retain my number when going to a new provider and that couldn't even be done correctly. Now I have been trying to do a sim swop for over 10 days and still has not been dealt with correctly. I have been calling every 2nd day where I either get put on hold and then the call cuts off 30 minutes later or I am promised that the situation has been escalated and someone will call me. Still no-one has yet to call and my phone is still active.</p>
