Jet account closure- a nightmare that doesn’t end

Don’t open your account with Jet, closing it is a nightmare. I have had the account for years and had cellphone insurance on it. In March I put in a request to close it and paid everything that was outstanding on the balance. A month later I am still billed for cellphone insurance, mobile content, airtime etc. For the past two months I have been on the phone with them trying to sort this out, and I am not getting assistance. Instead I have been transferred to a lot of different departments. Even now they are still billing my account. My cellphone insurance was R136pm. Yet in two months they say I owe them over R1000 for what I also don’t know.
