I have an account with Rain for Wifi service

I have an account with Rain for Wifi service. Sometime ago I got into a negative with this account owing 1 month of subscription. I contacted their offices on the 2nd November 2023. On the 6th November I made a payment of R559 via the App and to my understanding after the discussion with the representative from rain on the 2nd November, my next payment can be on the 1st December 2023. This morning they disconnected my services. I called in very nice and apologetic consultant btw... she said I owe R769, so until that is paid I will be reconnected, unfortunately it's out of her power. Imagine my disgust and anger!! 10 Minutes after my call to Rain I received 2 text messages informing me of my outstanding account!! Look at the business ethics!! I called in now again, spoke to another consultant, very arrogant!! They refuse to reconnect my services until I pay that R769....Now my question to him was...is that all I owe then my account is in order? His reply was yes. So now why is my account off??? My next payment is on the 1st December(as I was under the impression) They can fly a kite for all I care....they are an unprofessional, opportunistic and ********* business
