Challenge battle too frequent

I have this exact same problem, every game is a challenge battle .

I have even had people destroy me with 1x unit as they are so much higher level .

I like the game but now it is ridiculous as I can not learn if my strategy is working or not as most battles end with opponents just directly targeting my base and harvesters as my units are not strong enough to defend .

I just spent $22

on coins to upgrade me units a bit and now I feel like everyone is even higher level then before ?

it has ruined the game and is really frustrating playing a game with no hope of winning 95% of games .

please sort it out so we can at least be competitive
