Jet, Ed on, Rcs is milking money from poor people

I phoned Jet, Ed on and Rcs customer service beginning of September 2020 month to request my Jet account to be closed. I received an email of acknowledgement on the 15th September after I phoned again (mind you the email is not confirmation that is closed). Today 25 September I received an email that I have to R36.95 by 01 Oct 2020.I phoned again today to enquire about the amount and I was told is value added service (jet club insurance and also airtime something) which I don't even remember signing for them or applying for. That airtime thing, I've never since I opened the account received it on my phone. JET is reaping people of our little money that we have to survive with their pathetic service. I was told today that I have to phone another customer care to also cancel those value services but a lady I spoke to, don't know anything about it that she told me to hold and after holding on for about 6 minutes she hanged the phone without assisting me. I am trying to reduce my expenses by closing accounts because I'm no longer employed but Jet is making my matters worse now. Jet management is this how you milk money from us poor people.?
