Bad service/No service

I had a My Savings with Alexander Forbes, and I was supposed to receive all the money I had saved in 2020 on the 15/12/2020. After numerous communication with a lot of people, confirming that the debit order that went off on the 25/11/2020 was the last one and I will not continue with the savings in 2021, Alexander Forbes still debited me, I have sent emails to them from the 14/12/2020 but until today I haven't been assisted. When I reported that they still debited me even after I cancelled the My Savings with them, I was assured that after confirming that the debit went through, they will reverse it and process the reminder of my payment. On the statement I received on the 14/12/2020, I had saved R12 273.76 which was the amount I expected on the 15/12/2020, to my surprise, I only received R6 700.50. When I queried this, I was advised that they had a technical problem and will resolve this issue urgently, but until today I haven't been paid, instead, they only paid me the R1 100.00 debited on the 28/12/2020. I have sent countless emails, instead I receive automated responses and I will receive a call a day after my email and a promise that my claim is receiving urgent attention but no action. I have sent email to ***, Mthobisi Mthethwa, Kim Leonard, MySavingsApp. I got an email from Marcia Phago who also promised to assist, I got a call from Simon Madondo who also assured me that I will receive all the funds on Monday 04/01/2021. This has inconvenience me to the point that my insurance premium for the month of January is unapaid. I don't know who else to contact except to go even much higher to Mr De Villiers because I feel I'm not being taken serious.
