Cellphone line de-activated ***

<p>I have two lines with MTN on account number A ********** which includes lines ********** 463 and ********** 344. When i make payments which normaly done by internet banking is on one instalment of just over R700 and the the payment is split between the two numbers but i got surprised when I called the call centre they told me that the number was de-activated because of non payment and has been forwarded to Legal department, which even now I have not received any explaination as to what happened to the money I have been paying on the said account and how has the line been de-activated without my knowledge.</p>
