Over charged for energy

Hi, on the 30 of October I purchased 120 cantina twice for 100 crystals each. To my surprise I was charged 600 crystals instead of 200. I reached out to ea support on the 30th and they take 14+ hours to respond to anything and just ask generic questions and have no resolution. I just want my crystals back. Has anyone else had such a bad experience with the support and has anyone else had this happen to them
