Shopify Marketplace Connect

I am not sure if these folks are incompetent or just do not care, in either case, I would suggest looking elsewhere. My integration to Walmart and Amazon has been broken for over 7 months and it appears they have no clue how to fix issue. At times I feel I was the tester. Not worth your time if you are trying to build a business. Integration is not that hard, both amazon and walmart charged integration API; however, I know this was communicated to these people and they are just clueless on how to proceed. It is not that hard, if you know what how to do your job. I wonder how I can give a -5 star review.
