On April 14, fans spotted Taeyeon letting out frustration on her Instagram once again toward sasaeng fans whom, according to Taeyeon, are continuously calling her at 3 minute intervals, day and night. 

In her posts below, Taeyeon remarked, 

"Can I please sleep..." 

"Please stop"

"Can I please sleep..."

"Every 3 minutes... And for the past few days regardless of day and night... if I'd known they hated me this much

"I must've made a mistake, I thought it was a welcoming opportunity, and wanted to open up"

After research, fans of Taeyeon have gained information that a sasaeng who obtained Taeyeon's number messaged her on Kakao Talk first, then when she read the messages, began calling her. Taeyeon once picked up to exchange a few conversational words and greetings, but afterward, the sasaeng spread Taeyeon's number among other sasaengs, arriving at the current situation. 

We hope Taeyeon can change her number, or phone companies altogether, soon.
