bad service

I got a wifi router contracy with vodacom the contract ended may since than i was on a month to month payment plan the beginning of august 2020 i phone vodacom to cancel my subscription as i took out uncapped wifi and do not need the router anymore the consultant confirm that it has been cancelled when i switched on my router now to see if i can connect or if it is disconnected viola i am still connected which mean my contract is not cancelled and i still need to pay for september 2020 but i am very sorry i am not gonna pay for it because i need to pay my uncap wifi i dont have double money to pay for nonsense and what must i do with the data on the router if i have u cap wifi so it is useless for me to have the router now i must pay for something im not gonna use please fix this i am not gonna leave money in my bank acc for debit order if it goes through i will reverse the debit order and if vodacom rake my money i will take furrher steps because i am not paying for people who cannot do their work
