Vodacom/Finrite Insurance BAD SERVICE....

I have a vodacom cellphone insurance which i took out in 2016, when i started with the insurance, the number was prepaid until last year 2018 October I switched to contract. I was recently told that I'm no longer insured as the insurance was for prepaid. However I when I took out the the contract I was told it wouldn't affect my insurance for as long as i use the same sim card, debits are still going off even so. I visited the branch but nothing came out from the visit as the consultant could not reach the Vodacom Insurance department. I contacted the countless times with no help. They either never answer or transfer me from one department to another. I'm disappointed with this service.
