MOMO review for ABsolutely: A/B Testing

tl;dr site is now unreachable for returning customers. I try to avoid leaving negative reviews unless there's something egregious. A test was having 2 issues. 1. not aggregating sales results correctly. 2. Showing data "A" on site but data "B" at checkout, resulting in customer confusion. Not my first and only issue with the app, nor an issue bad enough to result in 1 star (though it's a pretty big customer impacting issue). 1 star because after ending this test in question, users can no longer reach our site (ERR_TOO_MANY_REDIRECTS). The only way to reach our site now is if the user clears cache, but realistically there's no way to share that information with a customer. The conclusion customers reach is that the website it down. I've had suspicions that how they handled A/B testing was a bit of a hack for awhile now, but it wasn't a large enough issue to act on. I messaged them via their support system on Sunday, got an auto response that I will be emailed back due to it being the weekend. It is now mid-day Tuesday with no response. Arguably I could allow for more time, but imo a site being unreachable is a priority 1 issue for immediate response. Uninstalling the application did not result in a fix.
