Telkom debit order issues

Telkom has debit my account 3 times one day the one went off the others failed. So they took my money and still suspended me for non payment. I called them so many times ask then can i send proof they said no still need to show successful. Few days back query account about 6 times no reply usless function. Called support again then the lady said all 3 failed they only counted two on 25 september and one on 26 september so they never counted the third one want went off successfully.. So lady said send proof already now still waiting..... Almost one month already.
