STROOHM does not manage public charge points from other providers. In that case, contact the operator of that charge point. The phone number is usually on the charging station itself.
You can also try starting the charging session via the STROOHM App. This is often a good backup if your charge card doesn't work.
Is the problem with your STROOHM charge card itself, for example at several charge points? Then submit a ticket via www.stroohm.com/helpdesk and include your charge card number, the location of the charge point, and the date and time.
