Cancel cell phone insurance and contract coverplus

I’m very upset with Vodacom, I’ve had a contract with them for over 4years, now I want to cancel an insurance on the contract or put a notice of cancellation cause I don’t want it going forward, An agent by the name of Thando Makgwale from Vodacom insurance department tells me she can’t because my account is in arrears of which I don’t have a problem settling when I pay my premium this month. She says she still can’t meaning plan is to dig a deeper hole in arrears which clearly benefits Vodacom and not considering me as a client or putting the client first. I’m disappointed and this is just the beginning my request was simple, cancel the cellphone insurance as well as the contract cover plus. I’ll be happy to delete this review. It is just my cry for help.
