Nurdtyme review for CS Amazon Integration & Sync

I used this App for over a year paying $29 a month. Had issues at the beginning and support tech named Olivier would fix it right away. Now over the past month inventory wasn't syncing with new items listed on Amazon. I put in a ticket a some new guy answers and asks a question. I would reply and then no answer. A week went by and I put in a new ticket and he would ask a question again and I would reply. Then I wouldn't hear from him again. At this point I'm getting frustrated. I put in another ticket and he asked another question again and I replied. Again no answer from him. Over 1 month of this goes by. The negative reviews are correct with this app. Customer Service is horrible. LOOK SOMEWHERE ELSE!
