Change of contract/Debit

I took an insurance with Unity Car Insurance and from what the consultant read when she called me and what I got as a hard-copy were two different things. Consultant said my cover include Car hire or they will give me R1300 if I decide not to hire a car. I requested call recordings and I was provided with call recording but to my surprise half of what we spoke was covered in those recordings. From what I know my monthly premium is about R1500 but on top of that amount they debited R177 of which I wasn't even aware of. Today I got an sms stating that they didn't get their monthly premium yet they debited on the 28 of December 2015. According to what we both agreed upon is that my Access fee will be R10 000 but now I'm being told that my Access fee is R13 000. So all I want from Unity is that they must stick to what we agreed upon and another thing they must send me both Call recording and the Hard copy of my contract. And again they must explain to me as to why did they debit R177 from my account.
