Unhappy client

I was called by one of their consultants who told me about renewing my contract with tem and that i can cancel any time with no fees charged. Now I no longer have a vehicle and been trying to cancel with them since March. They only provide me with reference numbers but never provide me with feedback. They still continue to debit my account, i tried stopping their debit they change date, amount but never get back to me about my query. Their actions are causing unnecessary charges in my account as they debit amounts we never agreed up on or dates that i don't get paid on. Last ref I got :Dear Client Your enquiry reference number is :Dear Client Your enquiry reference number is : CAS-***-W9N1
