I always use Paypal because they have buyers protection, and this has already saved me countless of times.

Would like to see if this is also offered in the Wero ecosystem?

It isn't. WERO is little more than a wrapper around SEPA transactions. They literally tell your bank to make a transaction. They are not a bank themselves so they never see the money or could take it back. That means the only one who might be able to help you is your bank.
