I CANNOT win games of Mahjongg Sanctuary

Hello;

   I need help desperately. I have heard of other players with this issue; and believe it's a bug in the Pogo system while playing certain Mahjong Games.

I absolutely CANNOT advance in many levels of Mahjong Sanctuary (among others). I am currently stuck at level 435. Have been playing for days and cannot win even one game. Many matches I have only matched ONE SET of tiles and it's no more matching & I have to restart /play a new game.

   MANY others have said the same thing. I contacted help several times, and once thru live chat. They said there was nothing wrong woth their end and it was my computer. It doesn't matter what I play in (Chrome, Firefox,etc.) the game runs the same way. It also has a habit of changing tiles - not sets; the number set ups as many as 5 times before I can start to play.

  My membership is due to renew soon. I am highly frustrated & can't see renewing for $40 when I can't play games I enjoyed before Pogo changed to this new Format. Even in the "old" version now, I cannot get the mahjong Games (a couple different ones) to set up & play so I can win. I am tired of even TRYING to play for badges (now Pogis -silly things they are), And I have complained several times over about this. 

   PLEASE, can someone tell someone in Pogo to FIX this situation.? The last time I complained, I ha not trouble playing for almost 2 months. Now it's doing the same thing again. 

Thanks for your time.
