BAD Bad iwize/old mutual

At the beginning of last month I cancelled my policy ***) via email three times. Today they just deducted from my account. I phoned them ***) 6 times and used up my airtime. I reload and twice they just slammed the phone when I said I want to cancell. So 8 calls and nothing achieved. This is not my first bad encounter with this bunch.......and they want me to give a reason for my cancellation hahaha. This is not an acceptable behaviour of such a big company. I urge the public not to support iWize/old mutual they want your money and then they leave you to drown.
