Insurance products on Edgar's account

I was charged some insurance fees on my account. I had not app**** for these insurance products.

I sent a number of emails to Edgars and there has been no response. I visited Edgars at Mall of Africa to cancel the insurance products. After numerous calls someone told me the insurance products had been canceled. I asked for confirmation of cancelation of these products and Edgar's staff could not provide this. I am not sure if my case has been resolved since no confirmation was received. My emails have not been responded to yet.

I received some document with codes that I do not understand and the staff said that was the confirmation. I am wondering how I can really be sure that my case has been resolved.
