Decreasing response rate Day by Day

[designer_zunaed]

Hello everyone,
recently im facing a problem with my response rate. My average response rate is 1 hour. i don't get that much new buyer messages, but when I get i try to reply so fast.
but recently i have noticed that without getting any new buyer messages my response rate is decreasing day by day. Every 2/3 days my response is decreasing 1 %. i lost my level Two for this response rate issue. 
i checked my spam messages. there is no such message in the spam folder. even i do not have any unread messages. 
can anyone please help me with this?
