Worst service and ****mers

Yoh I don't know if I should say I have been ****med or what by Rain, last month they tried debiting my account so they, say instead of the debit order coming out I get a message with a link to say they didn't get any payment, because I use it for work I immediately went in to the link and made payment. Then they disconnected my data and said they could not see any payments, I sent them proof of payment, for the whole month they have been confirming of seeing the proof I sent to them yet they would keep on disconnecting me and I had to call eveytime. Till one agent confirmed that, everything is in order. Then I was surprised month end they double debited me, I called them again to check what's happening they said its because I did not make any payment in July I confirmed I did and send again my proof of payment and the agent I spoke with said they will confirm, till today I have not received any confirmation email no refund, I'm now getting a message that I owe them R64 and I must pay to avoid disconnection, I tried calling them the machine keeps on repeating the options to choose instead of being put to the relevant department, I'm still waiting for my refund, there's no Communication nothing, worst service I've ever received I believe this is happening because I'm a woman. As I was writing this report I get more upset because an urgent pick up and left me hanging for 20 minutes without saying anything, please refund me and advise me further if you don't want me to use your services coz the last 2 months have been a nightmare
