Welcome to the community, Aleksvch!
It’s really annoying when a technical error on the website charges your card four times instead of just once.
Please note that this is a customer forum where customers help each other. We are all regular users here and have no access to Sunrise’s customer systems or billing data. To get a refund of the overpaid CHF 30, it’s best to contact the hotline directly at 0800 707 707.
Cheers, Cosmo
