Cancellation of policy 11 months ago

I am really at wits end. My mother has got alzheimers, bedridden for years, and I am her power of attorney. I cancelled her car insurance (OT ********** 5) via phone (after submitting a lot of documentation) on 30/3/2017, then again (after realizing that it was still going through on debit order) on 14/8; again on 19/10; again on 2/11; and again on 14/11 (per email). It is still running on debit order!

My mom do not have a lot in the bank because she is a pensioner. Every time Outsurance takes a debit order and there is no money in the account, she pays R140 fine for 'dishonouring' the debit order. And... then Outsurance will try SEVERAL TIMES to run the debit order in one month!

Outsurance is literally *****ing from my pensioner Mom by not doing their job in cancelling her policy as requested. Not only that, because they keep on running the debit order (by the way, I can not stop it at the bank), they are costing her money in bsnk fees, and their failure to do what is requested is reglecting very negative on her bank statements. Outsurance is costing her over R700 per month in the premium and bank costs that she can not afford and do not need or want.

After calling again, I was informed that I have to send 10 months bank statements and all of the documentation AGAIN! Surely this is lazy as they can easily see on their system what monies they receive from where for 10 months?

I really do not know what to do anymore.
