5th of the Month still no data no airtime

My top-up account is late every month for data and airtime. Today is the 5th and still waiting!! I have to go trough all the expense to load data and airtime all the time. I was in a credit of more than R1500 and again they took of more than R2000 out of my bank account. I have been battling to sort this account out since last year August 2014. Eventually last month they sorted it out. Or so I thought. Now this month back to square one. Fire all your accounting people for they are useless!!!<br> Fix my account!!!
