Billing

<br> Thank you for your response:) my account was dibited with 2 895.98 this morning. <br> <br> My first billing that I recieved on the 01/12/2014 from MTN since migrating from Nashua was R 694 but when I checked my billing statement I was charged 2 015.98 for Packet data calling which was cancelled I believe because it was an error.<br> <br> Invoice for 01/01/2015 was 2 467.76 and I was charged a whole lot of things that I do not know what is it for.<br> <br> Invoice for 01/02/2015 is 2 895.98. In february I did not go to Swaziland. My phone was locked on the 5th of February. Even while I was on Nashua mobile roaming in Swaziland I have never paid this large amount of money. Why is it when I'm migrated to MTN my bill skyrockets to this amount?<br> <br> I dont even Know what is packet switched data calls.<br> <br>
