Rain call centre agents doing their own thing

Tried changing my debit date from the 25th of every month to the 1st of every month as my salary is only paid on the 26th. The agent I spoke to on the 25th of March informed me that I will have to make another payment today 1st of April if I want to change the pmt date as the 25th of March payment will be for Feb billing...... how does that even work. I have not missed one pmt since I got wifi with rain. So in my mind I missed Feb and March payments. I told the agent to leave the payment date as the 25th of every month but she still went ahead and changed it to the 1st - meaning I have to make a payment today the 1st of April for March. So 2 pmts in the span of 5 days 🤬🤬🤬🤬🤬 Tried talking to the call centre agents to change the date back to the 25th but am told I have to pay the "outstanding amount" before they can change it. I did not agree to change it. Now I will have no wifi and no way to work from home 🤬🤬🤬🤬 Guess I should have listened to all the bad reviews about the horrible service this company gives.
