No, there is no number to call.

What is your problem? Maybe the Community can help. Otherwise you will get advice how to contact Customer Support. 

My phone was stolen, so I lost my pass and now I have a new phone. I already chatted with the chatBot, but it didn‘t work.

Only Customer Support can help you to disconnect your pass from your old phone. Write your pass number when contacting them through this form.

Customer Support is currently overloaded with requests so you will probably have to be patient to get help. Please let Customer Support know what date your travel will start so that they can prioritise your request correctly. 

Thank you !!
