Disconnected Many Times in VSA without no reason

Hello, many times i accepted disconnection without no reason in VSA before the game started, but today when I hardly reached 19 stars in VSA it disconnected me again 2 times and I have losted my progress once again..

NETWORK CONNECTION IS ABSOLUTELY FINE AND STABLE as it works many times normally when i played. 

Could you please explained me this kind of behaviour? It's the way how to ruined the players from EA or this come from Cheaters?

I am very very disappointed and shocked after so so so many hours I invested in this game.

Thank you
