Bad Service and Unfairly Handed Over and Charged Penalties.

In 2020 I lost my income due to Covid and I was unable to pay my montly premiums.I phoned Netstar and informed them and they did nothing about it. They continued trying to deduct every month from my cheque account and it was bouncing leaving my account in a negative balance every month. Immediately when I started working I phoned them and made arrangements for 6 months for the amount that I was in arrears with and I was advised that the account was handed over already. On the last month the company they handed over my account to deducted the debit order, 3 days after Netstar tried to take their debit order without even informing and that happened in July Month. Immediately I phoned them trying to find out why are they trying to take funds from my account twice in one month. I was then informed that they activating the account again since I have paid up my arrears, but why not informing me in advance so that I know. I then asked if they going to activate my account now the lady that was helping me did not answer that question and she did not even explain their processes from there. She just said Mam are you aware that your account is in arrears again. I was so shocked she said for the past since months you have been paying your arrears as a result your account is behind and the amount was over a thousand. I mean why was I not informed that I am still getting billed for the normal premium every month for the account that has been handed over and how is that fair. I told her I am really not happy with what they did. There is no clear communication and guideline she just dropped the phone. Two months later they handed over the account WITH A BALANCE OVER R6000 and they cancelled the contract and charged me a penalty again without even a notification. This is really Unfair and this is ruining my credit score and rating. there is no communication from their side they just do as they please at our expense.
