Hey @Diana Wamai 

Many countries switched to US dollars while adjusting to 10.99. Unfortunately, this decision was made in the management at deezer. 

Oh okay. It is a sharp price increase from$2.99 to $10.99 per month I thought that was unusual and thought maybe it's a glitch on my account. Thank you for responding!

Doesn’t worth it right? I wonder why this sudden price hike.

Could be a reason:
