Money added on account

During lock down my partner got behind on her vodacom data account, we received an account beginning of Dec 2020 with an amount on 9th Dec 2020 we paid that amount in full with an extra amount of I think R60, when I phoned the accounts department I spoke to a lady who told me the phone will be turned on in 24hrs and the next pay date will be last day of Jan 2021 and I must pay an extra R10 for reconnecting fees, now we have received an account for R310. 89 outstanding, we put in a dispute and got a sms saying the dispute was closed Noone contacted us or anything it was just closed, this amount isn't even what we pay a month!?! Noone can tell us what this is for but if we don't pay it then the phone gets cut off. How on earth does vodacom work??
