Horrible and misleading service!

When I started using Rain, I like the fact that it was not on a contract basis and if I didn't want to use it for the month then they would turn off my service and I'd pay when I wanted to use it again... or so I thought. I had not used my rain for over a month and when I wanted to make a payment now to activate it again, I had been billed R500 ! When I called to enquire as to where the additional R250 is coming from, they told me that I was still connected to their server and that I had to cancel it . I've never done this before and never had this issue before. Theve always advertised that if you don't pay then they would just switch off the internet, now all of a sudden, they keep the services on and just run your bill up . I never even knew it was on because the last time I tried to use it it was off because i had not made the payment ! The customer service people were of absolutely not help! Apparently they don't have a direct line to the billing department, an absolute joke. Would definitely not recommend ! Horrible service !
