Subscription not working

I have had deezer premium for a very long time and usually have no issues but at the start of the month i was charged like always except my deezer is showing as the free version. I have attempted to restore purchases but am still being shown the same free version. This happened after i was randomly signed out at the start of the month. I haven’t had time up until now to contact you but it has been a major inconvenience and i am very upset that i have paid for a service i am not receiving. I hope this can be resolved quickly as i am travelling tomorrow and have severe anxiety which is only calmed by music when i am in public. Thank you
