Supersonic causing chaos

I can't really rate their service cause there is no service. I was a Nepic subscriber and had no issues, they served their clients well. Why all of the sudden the news that Supersonic bought Nepic .. why destroy a good Company who was always willing to go the extra mile. After numerous emails and whatsapps .. I cannot reach them. Is this how they want to start a relationship with the clients of Nepic? They keep on sending me the incorrect invoice and tell me that I am on 10mbps, which we changed in March as our 24month contract ended. It seems as if no one has a clue, why then buy a company you have no idea of how to run it, everythjng Nepic employees worked for is going down the drain.
