False advertising

I subscribed to Datasim's unlimited data sim, received sim card on the 4th of June, on the 18th it was suspended this is after I have been using it for Facebook and twitter only since you cant do anything other than social media. How can an unlimited sim be cut of from only using social media, datasim are *****s and will be taking this further as I paid for 30 days not 14 Days.People must be wary of these **********
