STILL Paying for a policy I cancelled in 2013

I had a vehicle policy taken out with FFW around 2011/ 2012 and later cancelled the policy again because i sold my car in October 2013. Today , 01JULY 2019 when checking bank statements I called to query a debit order i had no idea i was paying and what for. Turns out, after cancelling my entire policy, FFW has still been taking my money for dents and scratches 6 years later, every month for a vehicle i don't own. When calling them, I was told that I was supposed to have phoned a complete different department after cancelling the first policy and cancel it there because its a different policy FOR THE SAME VEHICLE. In my opinion that is completely UNACCEPTABLE..are you not ONE company? When a client calls to cancel a policy and the reason being SELLING THE VEHICLE, it is the operator on the phones duty to cancel the entire policy as i had requested. I was unaware of the money still being taken which is theft in my eyes. No contact has been made with the dealership i worked at via phone, as i have confirmed this afternoon, and i was told they delivered post to my residential address, which in my town does not happen. Post is taken to the post office... If i was "unable" to contact for the last 6 years why still comfy enough to take money ?? This is unacceptable as i too deal with clients daily and will not accept the excuse that i should've called a separate department to cancel dents and scratches policy, when i took out a policy it was all as one policy from one insurance. If it was from a complete different insurance company 100%, I would've called all of them, but you are one company regardless of the different departments. FFW has taken over R9000 from me for a policy i have cancelled 6 years ago, to date. This matter will be escalated to the relevant ombudsman if my money is not refunded as requested and dealt with telephonically. This is unacceptable from a reputable big company like FIRST FOR WOMAN, IT IS THEFT.
