NEOTEL DATA CHANGED NO NOTIFICATION

I have been using neotel data to run my outlook. Today for some reason none of my sent mails were going through. when I queried with neotel they told me their system changed on the first of Nov and the current smtp settings no longer work. When I asked why I wasn't informed they said they only contacted contract people. So it seems I cant now use the balance of my prepaid which will only expire in April 2016. No one at the call centre had answers all they could do was laugh !<br> BAD BAD BAD SERVICE INDEED !<br>
