Poor service/communication/billing.

Several years ago, I cancelled debit order payments and initiated manual payments. Out of the blue in August, an unauthorised debit order was put through, resulting in my bank charging me an honour fee. Query ref 1- ********** ********** logged 29 Aug at 09h01. No response received. I followed up 19 Sept at 09h20, went through 4 service agents, 27 minutes on the line - to be told the matter was closed! No effort made to resolve, no communications received. This is typical Vodacom ostrich head in the sand service!
