My debit order boucned on the 5th of Feb, I think paid cash, and it was recorded on the 7th of Feb. On the 14th of feb i get a notification that my account is in arears, yet, when i call in, they say they have recorded it successfully on 7th feb and it was an accounting error, i should ignore it, and a case was logged ********** 6. On the 19th of feb, i get another sms and i called in. They say they will escalated it with accounts. On the 20th. I get an EDO payment collection on my account and money is taken off my account. Yet i am not in any arears but my credit score and everything is affected by this. I complained to a manger and he said accounts/billing does not have phones, they only communciate via email. What nonsense. a billion rand compnay and the accounts department do not have phones. I want a refund, as i have been charged LITTLE CHARGES FOR THE EDO PAYMENT
