A short while back I cancelled my service with Altice Mobile. There is a pop up from Altice on my Suddenlink.net. It gives me an eerie feeling that Altice will be billing me for something in the future. I had a very difficult time getting cancelled. The last account number I used was 9882. Please let me know if I am cancelled. And take that annoying pop up off my Suddenlink.net account. User's recommendation: Make sure your information is compatible with browsers such as Edge, Windows10. I had to pay a $291 penalty because so much time was consumed in cancellation.
