Rain has no heart and unauthorised debits

Worst service ever !!!! I tried so many times to change my card and use my Capitec Bank account and not my Nedbank card ad the Nedbank card is only for my rent. With so many attempts on Rain website it says processing. I assumed it was sorted and my new bank Capitec Bank account would be the new method of payment. This morning I get a message fr my Nedbank saying Rain took R958 and R498 from my Nedbank account instead of my Capitec account like I wanted. So my sistér send me tent for my flat which I pay on the 25th of each month so now Rain took it and now I am not going to be able to pay my rent and will be out on the streets with my two kids all due to Rain not listening and their system failing me. How do you sleep at night knowing you put a family out on the streets. I have all the money for the arrears amount on my Capitec Bank account which I tried and assumed it would be loaded as your Rain stupid website said processing new card details and method. Then I call Rain and a heartless consultant just says no refund can be done and says sorry so I asked her for a place to sleep for me and my kids as we will be on the street now. How can a company be so heartless and no empathy for customers no wonder they losing customer after customer. I want my money back or I will take this further I will not sleep on the streets with my two kids. You guys make me sick I want senior manager to call and sort this mess out it's so unfair that I get punished for your website faults.
