Free version gets eaten up fast with spam calls, I upgraded to next version, but still get too many spam calls using my quota. Tried to deactivate/unsubscribe, good luck finding how to do this because it still will not let me deactivate voxist. I looked up feedback and even followed their step by step direction but it does absolutely nothing. I sent a message and was told to follow the steps to deactivate it, which I did, hence why I contacted support.
