Unknown Charges

Please let me know as to why you are charging me R877.35 for collection cost levied?<br> You have not done anything out of the ordinary as my account is paid timeously monthly via an automatic EFT. Yourll also kept on calling me about an unpaid account, but did not realise that a new account number was created without informing me. Upon investigation the consultant found that my account was up to date and paid to the normal account. Can you please reverse this charge or provide me with a valid reason for this transaction.
