Aliwei Communications vs Teliax

I had used this service provider 10 years ago with great results. Recently, I needed a new VoIP line so I tried to use them again. I have been greatly disappointed. They still had a great price point and signup was quick and easy... but .. that's it. For the past year I have had my service just stop working either from their proxy servers being down or finding they have not properly processed payment ( my bank confirmed ). Calling or emailing support is a waist of time, you will never get through or get a response. Their payment system is unreliable and if a payment is declined during their outage, they cut your service, it's automated with no grace period. This has now happened twice in one year. I now am trying to close the account but can not since the web site function to delete the account fails, i get a message to contact support... No response.... I have had to resort to having my bank stop charges from them.
