Billed on the incorrect date

<p>I have a contract with Telkom mobile for over a year now and I asked to be billed monthly on the 20th and reason for that, "dare" because its the day i get paid, even a pre-school child would understand that. Then suddenly my account is debited a day before my salary comes in and when I ask I'm tol about the billing department... Hello!!! Why couldn't the clever billing department initiate debit order any day after the pay day rather than before...???</p> <p>I'm so frustrated now because I am in a process of changing my car and this matter has just made things worse for me as my bank credit profile has moved from grween to RED with an account that was once in access.</p> <p>I need an official letter stating that it is your fault so that I can use as a motivation with the bank.</p> <p>Contract cellphone: ********** </p>
