Money reimbur*****t over a lapsed insurance

In January I have called Abacus to find out about my annual premium increment, that's when they told me that my insurance had lapsed in 2022 and I have been paying this Policy all along. I called them and they took me from pillar to post, and that's when I have decided to send them an email to their customer care service. I did not get any reply then I send them emails to all their different departments, then I got the response letting me know that their investigating the matter. It took Abacus insurance 4 months to come back to me and I am still waiting for them to reimburse my money that I have been paying all along whole my insurance had lapsed. I have send yhem all the necessary documents needed for my payment process but I am still waiting for the payment to go through. Abacus has got the tendency of not responding to customer's emails and definitely over the phone you will never be assisted. They told me that their payment process is taking over 30 working days after sending them again many emails to different departments that's when they decided to inform me.
