Very questionable way of dealing with the customer. We have booked a holiday home in a Landal holiday park. Due to the current situation, the stay was unfortunately not possible. For an alternative date or reimbursement, we received the instruction to contact Landal directly after several e-mails. However, no one can access the booking or make any changes here. Unfortunately, when we contacted Landal again, we were referred back to Landal. To make matters worse, it is not possible to contact us by phone, which, strangely enough, is only the case with Wolters Reisen.
