Poor customer service

<p>I am moving overseas and needing to cancel a contract, i have been tp two stores, and have called the cancellations centre 3 times (over 20 minutes on my cell phone) and am still awaiting the promised email with the amount i need to pay to cancel contract. This is really poor service. I am actually wanting to pay out my contract and am struggling to get it resolved. I also emailed the retentions centre twice. What else must i do?</p>
