Using Netstar's portal for changes is useless

This issue is ongoing since October 2015. I changed my bank details three (3) times on the portal. I even sent a screenshot of the confirmed change to their [Email Removed] email address (TWICE). <br> Netstar obviously doesnt want my money, they also never reply to emails. All you get is \This is an automated acknowledgement that your e-mail has been received by the Altech Netstar Customer Service.\"<br> <br> Please fix your records and collect my installments! Should I come to your offices and beg you to do so? <br> <br> Note: I am already shopping around for a new supplier."
