MTN CONFUSED AND BAD SERVICE

my phone line was blocked becaused i missed a payment. Ususally as i understand, a line gets soft locked first, not hard locked immediately. I made the payment as the consultant gave me an amount and she said if i paid this they will open my line. i phoned again and then the amount changed and is now more. I made that payment too, They refuse to open my account as they calculated the current amount as to be paid to (current amounts are not payable yet as the account for that specific month is still running) arrears has been paid and now they notify me i have to wait 3-5 working days. each time i speak to a consultant, they have different stories. i can not wait to cancel this line and rather go back to vodacom
