bad planning


i have bean a revolut customer for just over a year now and like many people who use this service i travel. I use a sim not from the uk .your new app has drastically removed a great deal
of countries which can get sms message to log in to the app.I now find myself locked out of my account. DID anyone at revolute not think of sending a sms massage warning customers of
these changes . Even worse it is practically impossible to get in touch with customer service.
I sent a direct message yesterday and no response . can someone please help
