Spa Och Poolbutiken review for Fortnox by Uniwin

Customer service is among the worst sadly, my app stop working on 2 of my platforms, they are connected and all looks fine both in Fortnox and Uniwin, but nothing is being sent to Fortnox. Have contacted support several times during a week but no support, very hard to keep this app when we have 200 orders per month and no service.
