Double debits

I have a cellphone insurance with Finrite for my BlackBerry Q5 that I'm supposed to be paying R60 monthly premium for, but to my surprise I'm being billed R132 monthly and I tried following up with them but no feedback. Firstly they requested I send them my statement on 20-11-2015 of which I did but still I haven't been refunded, I tried following up but nothing up to so far. It is very annoying to spend lots of money quering this problem of which i'm paying for the service monthly, they said it was sorted in December but on the 02-01-2016 they debited R119 and I don't know why because my premium is R60 monthly, we can't be dealing with lawyers for such small amounts, get your house in order please!
