Incorrect monthly deduction

<p>My contract stated that vodacom will deduct my bank on the last day of every month. During the beginning of May I received sms's saying that my account is not paid and I must make payment. But the money is still in my bank account so I phoned Vodacom and they said that they tried to deduct on the 28th of April and there was no money available. The last day of the month was the 20th and not the 28th. I said the money is available and please deduct the money and reverse the R100 charge for there was money available on the last day of the month. They only deducted the money off my account by the 16th of May. Today i received notification that they deducted R813 instead of R613. When i phoned them they said it is the charge for the 28th of April and then they tried again on the 30th. But my salarie was in the account on the 29th already so if they did try to deduct on the 30th it would have gone through. According to them they also tried to deduct again after i requested them to deduct money and it bounced again on the 15th but according to my records the money did go off my account on the 16th because the money was still available from the 29th. Payment debit orders are computer generated. And i have a contract saying it will go off on the last day of ever month. if it is a sunday or a public holiday it is not to make any difference in the matter for it is computer generated and there is no person behind the computer that needs to process the payment. I am no short of R200 on my budget this month for vodacoms incompetency. I would realy like to have my R200 back. This is unacceptable. Please help.</p>
