Unfairly treated and ****med b

I have been a contract client with Vodacom for more than 10yrs and I paid up 3 of my contracts and requested that the contract close. Vodacom closed my insurance of 2 of the contracts I had and I didn't make that request. I phone the call centre when I got the sms to let them know that I didn't make a request that my insurance be cancelled and they just told me that I has 24hour to move the to prepaid insurance and I pleaded with the consultant because I didn't have network so that i can print and sign the document and she said there is nothing she can do. The problem is that when I took the contract it wasn't packaged with the insurance and I took out insurance on my own with the help of vodacom but now they cancelled my insurance that I app**** for on my own which was not part of the package and I didn't even sign or make that request. When I reached out to the social media platform because they respond quick and they just said I need to speak to insurance and they insurance said that Vodacom cancelled when I paid up mu contract. I have been treated unfairly and one department brushes me to the other with a stinking attitude. I feel ****med by vodacom and I have been so loyal to them
