I tried to cancel and had the same problems you do. I was still being charged despite not being able to play the service and there is no human to contact. I finally canceled the credit card that was being automatically billed.
Qobuz Playing Games with my bill
I been charged twice a month since November. $ 14.11 on the 2nd and $14.32 on the 23rd.
There is no telephone number.
No email address.
They have a bot chat delivering solutions that can not be accomplished.
I will call my CC company tomorrow and challenge all the charges.
Meantime I just have one thing to say to the Qobuz people- KGFY.
Anyone else have the run around with these folks?
