TERRIBLE SERVICE!!!

We have a debit order that goes off every month for my contract phone. This month, like every other month, it went off on the correct date. Payment went through, money was deducted from our account. A few days later I started getting SMS's that my account is in arrears. We called customer service and they agreed that there is something wrong and that they have received our payment. About a week (and a few more of those SMS's and phonecalls) later, my account was disconnected. It's been more than a week now, my phone is STILL disconnected, we phone every day and they keep telling us it will be fixed within 24 hours. We even went in-store and they keep telling us we need to email bank statements to a certain address (which we've been doing, multiple times) TERRIBLE SERVICE!!
