Pathetic service

Initialy i made arrangement with Tshepo about the payment Tshepo which you were debiting the amount we agreed on and he said the last payment of the arrangement it is October or November all of sudden you started debiting my account twice.i spoke to several agents and I requesed the recording and feedback no one is giving me feedback.last weekend I called you and I spoke to this other lady she said I must discount she will call me but she never called. You service is very poor and I will escalate this to your CEO.i don't want to speak to speak to any agent now I need a manger to call me to resolve this.
