Insurance with the worst ever service

On 18 June 2024 I placed a review on Old Mutual Insure. Since then, I have had 1 call. The person informed me that they were aware of my complaint and that it will be escalated. I then received an email to which I responded. I did not get any further response. After a while I received an email with the sender stating that she was not at work because she fell ill. I have sympathy for her being ill, but I still did not get an answer or solution. I further fail to understand that a firm as big as Old Mutual, that no one else could attend to the matter. After this I informed the sender that I am cancelling the insurance with immediate effect. Since then, I have not received a single phone call or email. However, the debit order still continued. Old mutual even went as far to instruct my bank that I was not allowed to reverse it. This is the worse ever service I have ever received and NEVER suggest Old Mutual Insure to anyone. It is, according to me just another company which, because of its size can just walk all over people and take people's hard-earned money
