Rentoza be AWARE

I bought a notebook from Rentoza paying it of over 24 months. When I bought it my salary date was the 15th of each month but I joined a new company and my date changed to the last day of each month. When I contacted Rentoza to change my debit to the first of every month I was told I have to pay a penalty of R300 to change it. I've paid the 300 and for the last for month after many communications with their call centre they still try to put debit order through my account before the 1st. Today I received a call from them telling my I'm a week behind with my payment but my payment is actually only due today and within 10 Min after the call they locked my notebook remotely and send me an SMS that they will collect my notebook the day. I've been paying the notebook for a year now without missing a single payment and this is how they treat their customers. SO PLEASE THINK TWICE FROM DO BUSINESS WITH THEM
