MiWay service pathetic

Customer Care/Retention department is pathetic. They are very quick to sell insurance to you, and the service that they provided to sell is fantastic. But then, because I got a much more affordable insurance offer, I cancelled my policy with miway in JANUARY. They accepted my cancellation via PHONE AND EMAIL. But EVERY single month since then, they have deducted money off my account. I phoned and emailed them to rectify this issue in February, and told them that they were still deducting debit orders from my account - which means that now, I have been paying for TWO insurance companies. They promised in February that it was a mistake and that they would rectify it and that they definitely would not deduct money AGAIN. But once again in March, they stole from me again. Same as in April, they stole money from me again. Now, every time I try to phone, they make me hold for 20minutes before telling me that they will phone me back, nobody is there to help me. I am fed up now! 4 months now that they have deducted money that they were not allowed to take!! Not everybody can afford to lose R4000!! Phoning doesn't work. Emailing doesn't work. So now let's see what happens if I make it public.
