Aida opening a *****ster case against me, accusing me i sent them **** proof of payment

I started renting here April 2023 and was informed rent is R6000, within 12 days of occupancy was told rent is R6500 i fought as i had proof and then they decided to stick to R6500. Agent sent me an email to confirm that i should make manual payments going forward as they wont debit my account,which they debited. They terminated my lights until i send them proof of payment which i did. Agen after 24hours she sent me watsapps messages accusing me of sending them **** proof of payment and that the owner is opening a case against me. Unfortunately il also be doing the same as this is serious legal allegations/accusations. Agent confirmed they will be switching off my water and lights with immediate effect and also immediate termination of lease agreement
