Poor service due to psg not canceling as per request sent as per instruction from the consultant

After consulting with a consultant to change my medical cover in 2024 and submitting my application for the new plan for 2025 and canceling the two plans I had, they failed to cancel one option but canceled the other. They deducted premiums from me for 6 months. I noticed the deduction a week ago and addressed it with the consultant and was advised today that they did fail to cancel one of my options and my doctors were billing the medical aid provider on this old plan instead of the new plan. I was told to get my doctors to refund the medical aid and then I would get my refund if they are willing. Seeing that this was not a fault on my side which PSG is making it out to be my fault, I am requesting to be fully reimbursed for the plan I thought my doctors were billing on as this was not used. I demand 6 months premium back and for the cover that should have been canceled to be canceled immediately and I continue cover on the option I chose for 2025. It took over a week to get any feedback after several emails sent. I have never had issues with PSG until now and shocked at the feedback I received. PSG FAILED TO CANCEL THE COVER AND I DEMAND MY REFUND ON THE NEW PLAN. AS I NEVER UTILIZED THIS DUE TO PSG FAILING TO CANCEL THE COVER I HAD IN 2024.
