Misleading Information and Incorrect Billing

When I signed up with Car Track I opted for the R99.00 option. I am being debited for the R149.00 package. I was also told it is a 24-month contract only to find out it is 36 months. I have been contacting them at least once a month to have the billing rectified and to have the overdraft amount credited back to me. Every time I call and ask for a reference the operator tells me I should use the DATE and TIME of the call as a reference. When I call again and give them my previous reference then I'm told it's not a reference and at the end of the call when I ask a reference, I get the same answer to use the TIME and DATE of the call. I have been waiting a few months now for the recording, but every time I call, I'm told the person in the department is/was on leave. What utter nonsense is this. The last lady that assisted me said she will have her team leader/supervisor look into this and that she would be in contact. Three weeks have passed and nothing to date. I advised her that I would give her a few days, then I would take my story to social media.
