*********** Vodacom - yet again

How can a big company like Vodacom not be able to process debit orders correctly. My debit order date is set to the 1st of every month. This month the 1st was on a Saturday. I receive an SMS from Vodacom on the 3rd stating that the debit order failed. I call Vodacom customer care and the representative tells me the debit order failed because Vodacom don't process these on weekends or public holidays. They now have to ask the collections department to resubmit the debit order but I will be penalised an additional +- R100. I refused this and now on the 11th of September Vodacom are asking me to do an EFT payment. Ridiculous company with *********** staff.
