Ciao ​@JozefG92. I think the subscription links directly to your email account. Have you tried to change your email in settings?

If it has not been able to solve the issue, as you already did ,for Strava subscription enquiries, you can visit the Strava Support Center or email them at support@strava.zendesk.com. 

I’ve tried, but unfortunately, I can’t change the email.

I have already sent an email to support, but unfortunately, I haven’t received any response from them.  
Is there any other way to contact support, or did I simply lose the money I paid for a subscription that doesn’t work?

Ciao. Support will contact you asap. If your ticket has been correctly opened it's just a matter of time 

​@Vincenzo thanks, my ticket number is #3323189

I will wait for contact from support. 

Unfortunately, I still haven’t received any support from Strava. Can I expect any help, or did I simply waste my money and my subscription?

I’ve noticed that my old account, which I no longer use (and which probably has the same email address as my current one), has an active subscription. It seems that when I paid for the subscription, it was applied to that old account, even though I was logged into and using the new one.

Can someone help me with this?

​@Bryant, ​@Lola, would you please know the current ETA for Support’s response time? I know they're swamped but it would really help if Jozef could get at least an estimate, to know what to expect. Thank you!

Hello ​@JozefG92 - lease note that all account and subscription inquiries will need to be handled by our Support team. The Community Hub is  for general questions and information while our Support team will handle questions that require account access.

We checked with team internally and were able to confirm that you do have an open ticket at the moment #3323189. Our Support team will be reaching out to you in that ticket so please refrain from opening any more new Support requests as that will slow down the process. We thank you for your patience!
