Mis-selling and mis-qouted and account in error

In April/ May I went to Jet store because of the sms that I owe R347 and enquired about the amount. I was put on a phone and was told that Jet is paying Hollard on my behalf and as my knowledge I'm paying jet insurance R145 and I was paying R160 to avoid errors that I signed and underwritten by Hollard. I was paying the Jet/Hollard funeral insurance by cash to easypay/ref used for payments : *** Mis-selling and misquoted which led to debit balance that could ruin my credit score. I would like for the account to be cleared, refunded and close that policy as it was sold under false circumstances. I've stopped paying in April/May and they are busy sending messages that I'm behind with my payments after I've asked for the policy to be cancelled. How do I pay and for jet to pay on my behalf given an account with reference and amount of R160 as per my initial agreement? Due as of August R2658
