What a disgrace of a service provider

I am now paying 2 months of fees for a service I cannot use, all thanks to their poor communication. Nowhere does it say I cannot use my own sim card, and I cannot take 2 sims in my phone.

I had a customer service agent phone me to talk about the cancellation. I told him I was upset, the service I got from Vox was poor and that I wanted to take my services elsewhere. I explained how my emails were ignored, how Vox never gets back to me and how I have to keep following up. I explain that nothing gets resolved and I had to take it onto Twitter. His response was "Ok, have a great day". These people are sick and all they want is your money. No support, no after-sales service.
