Internet access OK, but severe security issues

The internet speed and reliability is pretty good, but I've noticed severe issues with account security. I consider my My edpnet credentials stolen by default, due to their short default size and most likely plaintext storage over at edpnet. Same thing with telephony, plaintext and not only that, it's also unencrypted so anyone is able to intercept ongoing calls. More than a year ago I've privately reported this to edpnet and it still hasn't been taken care of. What's more, according to edpnet the obvious solution to this plaintext communications and insecure password storage issue was locking down telephony registration to their IP range only, which pretty much defeats the whole purpose of VoIP telephony. This is a temporary bodge at best, and far from an adequate solution.
