Hello @korchihicham please get in touch with our Deezer Support Team and one of our agents will check your account in the system and let you know if there is something wrong. My guess is that prices have changed in your country and the price for a Family subscription is USD$17.99 now (193 Dhs more or less).
Thanks 

hello but normally if there has been a price increase, Deezer should notify us before. and in addition the increase should not be 3 times the amount we paid before.

All users were notified about a month ago more or less.
You should have received an email unless you have opted-out of any communication from Deezer.
Thanks

No i didn’t receive anything about this

@korchihicham you should have received the notification on the 15th November as I can see in our system.

Maybe the email ended up in spam?
