Don't get it!!

I've been trying to downgrade my coverage for about 2 months now. Their app doesn't let you downgrade your coverage and when you send a callback request they don't call you. I had to make it seem like I'm buying for them to call me back. When they did they said they have downgraded my cover and from the next debit they debit R500 and something but I've just been debited the original R749. Now I just want to cancel my cover and they won't take my call. I've been trying to call them since last week but they just put me on hold until I drop the call.
