Worst service Ever

I took insurance with Ackermans when I opened a store account with them. I had never missed a payment since taking the insurance. At the end of June 2019 I was retrenched and was asked to send them documents to confirm the retrenchment, which I did. I continued to pay account though I was no longer working as I was giving them time to resolve the insurance issue. All that I have been getting from them is that they don't get my documents which I always go to the store I'm order to have them sent. Beside having been paying my account I the interim, Ackermans took me to ITC saying that I'm a bad payer. I took the matter up with their head office who kept telling me that they did not receive the documents. I regret opening the store account with Ackermans
