Endless contract problems

<p>I have recently upgraded my phone and simultaneously changed my contract package, due to activate on the 1st of March 2017.</p> <p>I ahve now been notified that my account is in arrears (the money has always been debited straight from my account so HOW is this possible????) and my account has been cancelled as of the 3rd of March 2017. </p> <p> </p> <p>I have tried to speak to many consultants and absolutely no one is even close to being helpful. </p> <p> </p> <p>Please contact me ASAP to sort this out. It is unacceptable and I do not appreciate being accused of owing money without my knowledge when I have been a loyal customer. Absolutely disgusting treatment. </p>
