Outstanding policy increase resolution since January 2021

In December 2020- Jan 2021 i received an email staring my policy premium would increase. The increase was substantial and i queried it through the service@oldmutual email address and did not receive any feedback. I was debited the nee amount every month and everytime i emailed, i did not receive any response. I then received a response from Imraan, i responded to the email and still debited the incorrect amount. Lastly received an email from Venilla Naidoo who explained it all to me. She mentioned another division would call or mail me to quote me so i can revert back to my old premium with the previous cover amount. I followed up 3 times since then and no reply to my mail. And today i was debited the incorrect amount again!!! Now i am highly annoyed and tired of fighting over email. When i call in i am told there is an open case and someone will respond. I have been debited incorrectly for 6 months now and expect my premiums to be rectified and be refunded the difference of the amount that was debited vs what i confirmed i was happy to pay. The reference to my mails are Re: L1: K Moodley - Greenlight ***9 - Policy Increase Complaint --INTO***4-- - Ref. [PFCS***9] - Old Mutual Enquiry --NPCRM***1-- There are other mails that i am sure you will see in my history from the day i contacted old mutual in January

Please can this be resolved urgently or i will take this up with the ombudsman. This is not the experience i expect from a reputable institution like Old Mutual. Very disappointed!!!
