Bad Attitude of customer service and accounts

On November 2014 I stopped my debit order due to my salary arrangement. They still put in the debit order. Now they charge me each month for the admin for the debit order that don't go off. I pay my account each month electronically. But now each month before I pay my account they suspend my line and I have to struggle to get it on again. I pay my account prompt each month. Today I phoned customer service about my line and the consultant were so rood and off the 4 consultants that I spoke to not one could solve my problem. It is an outer shame that for a big company like Vodacom can not even solve my problem.
