purchased an Ottocast Air and reported a serious defect through the OttoPilot app'sAfter-Sales Help feature.I provided a detailed explanation, along with video evidence and log files.Nearly one month has passed with absolutely no response.After the latest app update, my support ticket completely disappeared, as if my case was deliberately erased.This is not just poor service — it is a total failure of after-sales support.Until customer issues are taken seriously, this product and company cannot be recommended.
