Arabesque review for PreOrder Now Backorder WOD

Quite disappointed with this app. I loved it at the start but for the past 3 months it's been sending my customers emails that their order contained a preordered product when it doesn't. So it has created a lot of confusion. I have contacted support 4 times and then I don't receive a response and they close the ticket. I then have to open another ticket and the same issue happened. Unfortunately I will have to look for an alternative application as I am not getting help to solve the issue.
