Rain Mobile will deduct your money upfront but fail decimally at customer service

For the past 3 weeks, I have made several attempts to contact Rain mobile @rainSouthAfrica via email & Twitter DMs requesting their help as well as refund and cancelation of my order, after paying upfront for unlimited data service which was never rendered. I want my money back and also need them to cancel my subscription as it seems they intend on debiting my account again on 1st May, although I'm still unable to benefit for service paid for. The 2 Rain agents that separately responded to my emails with questions - which I then answered, never came back to assist me / give feedback. They were of no help to me, and left me stranded. Hence I have resorted to seeking help here.
