Poor Old Mutual Service

I have multiple policies with Old Mutua for more than 10 years but since last year when I changed from persal payment to bank payments, they have failed to collect monthly instalments, there was a time when they collected R124 instead of R1 200, this was due to their system error because they changed their system and when I enquired about it they told me the system will fix it. Now they have been sending me emails threatening to cancel my policy. I went to the beach and spoke to the financial advisor who also enquired they promised to investigate. But during investigation I have been receiving emails saying my policy will be cancelled, I went to the beach we called the lady called Feiza who said the matter was going to be investigated, but during the investigation I received the email saying my policy is cancelled. Remember they are still investigating why they failed to collect money from my account but yet they cancelled my policy, they say that there was an insufficient funds in my account. I asked them if there was insufficient funds why didn’t they communicate that with me??? Secondly is there was insufficient funds why is my bank statement not showing any bounce back on a debit order??? As I write this review I don’t have a death policy they cancelled it while they are “still investigating “ and I’m yet receiving other emails threatening to cancel my other policies that I have been paying for for years now, including a life cover!!!!
