Payment Revarsal

On the 28 February I made a manual payment via customer zone platform. On the z1 March the debit went through of which it was a double payment. On the 3 March I inreactead with an agent by name of Fitihah requsting the refund. She checked the payment history and both payment are reflected, she further explained to me that as per policy I won't be getting the refund for the payment made on the 28 Feb instead it will carry over to the next month and there wont be any debit as I have paid inadvance.on the 2 March an insufficient money was debited on my account.I then submitted my query via chats and the agent I interested with was refiloe I explained my situation and she insited that I should forward the proof , advise her that I have a network problem can't she go through the payment history to Check. She kept on insisting and my time was running out. On the same day I again intereacted with Nokwanda her service was rotten she very unprofessional and sounded rude by cutting our conversation while we were busy. I then interacted with Karabo who assisted me by linking me back to Nokwanda whom I again introduce myself to her and explaining again she kept on pretending as if she is intereacting with a new customer. I requusted for escalation she requested me to be patient while she is transferring me I waited for two hours until she ended up the conversation without any further service. The service were are receiving from this service provider is rotten.the only time you are important is when you buy their services once you are their client you are nothing but a peace of *******
