Disgusting service from vodacom insurance

Where do I even begin. It's utterly disgusting to pay for a service that is not being provided. Vodacom Insurance is such a big service provider and I feel that they are taking advantage of me as a customer. I am not being treated fairly and information regarding my policy and insurance request cancelation is not being provided to me yet payment is being deducted each month off my account. Should I fail to make a payment then they will be quick to blacklist me but can't provide me with information I require. Surely this is not in line with TCF and I am not being treated fairly. I had problems when claiming from vodacom insurance an now after requesting for my policy to be canceled I'm still being debited. What is going? I have been a client for over 10 years surely that should count for something but it's taking them months to assist me. Do you not have any service level agreements or provide clients with time-lines or feedback. Why must I complain to be assisted. You are not doing me a favor I am paying and this is wrong. I will be taking this complaint to the OSTI along with all the proof of emails.
