Pathetic service FNB CONNECT

I got a message from FNB connect sometime September/October informing me that my device contract will be expiring 30 November and then stated my new subscription as the device would have been paid up.l called in and was informed l need to call in November since if l requested cancelation at that time would have to pay settlement and that November will be my notice period.I then phoned in yesterday and the agent first told me that my last DO would be end of December and when l disputed that she then came back and said there was a system error my contract expire 30 November. She then told me she was logging a query for me and advised the query was to cancel the contract since she didn't have access too and advised that in December l was not going to receive any data or minutes. I then got an email advising that l can't cancel l have to wait for the last DO to go off then call in to cancel What nonsense is that three different people from same dept dont know the procedures.why should l keep on calling to cancel if l told you already an not interested.the same way you sent me a message why can't you also put a note to terminate the contract on expiry. Why must l waste my money calling you. What about the notice period l was told about. You mean to tell me l must pay again end of December Don't u have enough customers to concentrate on than to force your services on someone not interested. MY LAST DO IS 30 November 2025 what you do after that is none of my business dont you dear debit my account.Just try it you will see
