Several tools don't work as advertised. Seller support emails me once every few days with the copy-pasted message of "We haven't forgotten about you!" but the issues remain outstanding for over a month. Automated review requests aren't being sent. Back-and-forth with support & now 10% are being sent, but several thousand reviews per day aren't being sent. Restock reports aren't accurate. Showing 0 units in stock when I can see hundreds of units on seller central. Alerts don't notify if a dimension change results in a higher FBA fee. An email saying "your product was 14.1111426cm length and is now 15.21111156cm length". So I need to check every ASIN after being notified? Whats the point of the alert if it's only partial information? Refund genie & customer support have conflicting information on US & CA FBA inventory. 1 report is generated, but our inventory in CA & US is separate. No instructions on how to file for 2 regions within 1 seller ID, and seller support has no idea (given answers saying no don't file in both regions, and yes file in both regions). I also reached out to the sales guy (Michael) who pitched helium10 and said "sellers your size need to be on helium" but unfortunately I didn't receive a reply. I've been going back-and-forth with seller support for over a month, still no end in sight. Couldn't recommend helium10 in the slightest. Has negatively impacted our business in several facets and their sales team can't even reply to emails with my concerns.
