Jet staff *******ly loading insurance products on my account.

I've had my Jet account for more than 20 years. Earlier this year, one of the sales consultants in the Carnival Mall store obtained my account information-pretending that she is checking if my card still works. She then loaded 3 insurance products on my account. Took my 2 weeks of fighting to get it off and I reported her. She was apparently dismissed. Since then, she clearly seems to have her colleagues taking revenge, because this happened again in June...again took my a week to get it off my account. Was told that the complaints department would give me feedback - still not happened till today. Just finally saw the amount reversed on my account. But what about the interest that is charged on this??? To my surprise my new statement again shows insurance products to the value of R411 on my account - this time 5 products!!! There is only one number to phone to complain about this, but they now refuse to tell me where and how these products were loaded (same with June incident) - clearly protecting their staff. I'm also suddenly not receiving my statements, so each time I want to know what is going on, I have to phone, then wait days before a statement is e-mailed. What is going on with Jet??? I need to have this resolved ASAP!! I'm at the point where I want to close this account just to avoid this *****
