Neotel Liquid Telecom not playing fair

They tell us to find other service providers as they are no longer in this business. Had uncapped WiFi. Once I give notice of cancellation, they block access, by changing password. I write to complain that I now have to buy data because they've blocked my access. They pretend not to understand what I'm talking about. Respond by telling me I've uncapped, like, yes I know but you have blocked me. So, I have returned their debit order unpaid. Ridiculous. Also charged me for moving to different flat, without telling me costs upfront, then do it a week after agreed date, which meant extra expense for data. But, am supposed to pay for that period! These companies expect us to just pay as if we don't gave to work hard for our income. Account number - R ********** 84
