Re I'm treated with NO respect from Gerhardt at Vodacom

I got a phone call from Vodacom Solutions department by the name of Gerhardt at 10.09am this morning, who informed me that vodacom will debit my account twice. I informed Gerhardt that vodacom had already taken money off my bank account and Gerhardt rep**** that does not matter, that if the monies of the double debit order is returned then all the cellphones data, calls, etc, will be disconnected, and Gerhardt even asked how much is in my bank. I have never felt so humiliated and been treated like as if I am no client to vodacom just that the monies will be deducted even though vodacom has been paid and that money must just be in my bank account to pay only vodacom. How disgusting that I as a client must be treated in this manner. It's made me see on the manner and behaviour, I'll never upgrade or do anything furthermore with vodacom.
