The Rain Internet Service Provider Money Pit

So I was having signal problems with rain because of lack of coverage in my area. I put my router off for the whole month and low and behold I got billed over R600 for my subscription (normally R480) that month. When I queried with the call centre via email they said they cannot reverse the payment (even though my statement shows I was only supposed to be billed for R123) I will have to cancel on line which I did and got a notification that my cancellation was successful. Low and behold end of the month comes round and they bill me again this after me cancelling and it has future recurring payments for the next few months. After sending another email to their client services because you can't phone, nobody has the decentsy to email me back. At this point I want my money reversed and this contract cancelled. It defeats the purpose of a month to month contract and at this point my router is off again because there is no service. This tends to be a trend in our country. Exploit the guys that are trying to better their lives. Absolutely pathetic service provider. Do not ever sign up for the rain money pit. You will experience more in the rain then ever before.
