Billing of my MTN Accounts

DEAR MTN <br> this is a very upset customer, I have been a customer of Nashua Mobile for almost 5 years and i had no problems with them until i have been swapped with MTN Direct. I have been on a top up and also had a call limit with Nashua since MTN taken over my account my bill has been increasing continuously. I have been querying this every month and i had no response what so ever. <br> no one in the call centre can assist me every time they say IT IS A OPEN LINE, OPEN LINE AND THEY CANNOT CHANGE ANYTHING FOR ME. I said on numerous occasions i do not want an OPEN LINE. As a customer i paid for my account every month with no default. this time i received my statement states bill amount R3100.00 HELL NO I AM NOT PAYING THIS NOW I REFUSE COMPLETELY. I AM NOW REALLY GOING TO CLOSE THIS CONTRACT PHONE AND I REALLY DO NOT CARE WHAT SO EVER. MTN CAN PUT ME ON ITC AND ALSO LOAD A JUDGEMENT ON MY NAME I AM SO GHATVOL IS NOT EVEN FUNNY. I EARN A SALARY OF R10K I HAVE A FAMILY TO SEE TO I HAVE 2 KIDS AT THE AGE OF 2 AND 6 YEARS OLD. HOW DO YOU EXPECT ME TO PAY A BILL LIKE THIS. WHEN EVER I CALL MTN ON 808 THEY KEEP HANGING UP ON ME. THIS IS NOT THE SERVICE YOU EXPECT FROM A PROVIDER.
