Rain - Poor customer service

Rain allows the customer a period to test their connection and internet speeds. After which of the customer is happy he/she can opt to keep the sim and pay or cancel the sim and not pay the R250. I chose to cancel due to the poor connection and slow speeds, and rain emailed me and told me as of the 1st of December my sim would be cancelled. However on the 1st the R250 was deducted from my account and to make matter worse I have tried to contact Rain's customer support via telephone and by sending 3 emails and yet have still not received and feedback or contact from them. It has been 5 days and this is really really poor service.
