Unfair practice

So i took out a retrenchment cover at old mutual and before my policy could mature i got retrenched, i then submitted my claim forms several months later with notion that i had submitted after it had matured, it was then rejected we had our fair share of dispute with the consultant which didn't materialize.

The most disturbing part about all of this is that till today old mutual still deduct money from my account for the same policy and claim they had rejected, i have emailed and called to find out why and no one can give a good enough reason as to why am i still paying for a service that i don't need clearly there is no income i am protecting and also what justifies old mutual to continue to deduct money out someone's account for a policy that was rejected, why am i still enduring these cost why must i pay for something that was rejected is this fair business or is this allowed, what protects the consumer against corporations who just use their big names and tells you that you can go and speak to the complaints department or the ombudsman if you not happy i mean i for one have a lot on my plate i need to put food for my family and still fight with big giant of a corporation for taking the little i have i am still unemployed and its been more than a year i took out this policy that i am still paying for which was rejected
