Poor Communication with Clients and not refunding money

A *****ulant policy was opened using my personal details and for 6 months it debited money from my salary. Due to circumstances I only picked up this problem in September of this year and it had already activated in March. I immediately contacted the company and submitted all evidence on 15/16th September 2021. I was assured they would refund me immediately while doing the investigation. It is November and I have received no refund and no communication from any representative, instead I have called multiple times, emailed, have gotten no response. I want my refund and this issues sorted, I am not willing to wait another 6 weeks for my money. They have all the evidence and affidavit from me. I want answers and my money.
