Poor aftersales service

I bought an H50 Zoom phone early this year. The first unit had a flickering screen so I exchanged it. The second unit has an issue where it doesn't always show notifications for emails and Signal messages unless you physically open the apps, although I'm aware of this happening on other brands so I emailed customer service asking if there might be a software problem. The response I got was send it back to the shop and no-one bothered to answer my follow up question.

Then last week the fingerprint scanner wasn't recognising my fingerprint for a day, I emailed customer services again asking for assistance and literally got one line in reply - take it back to the shop. It's out of the shop warranty period and in fact would have to go back to the manufacturer but no-one bothered to ask for information as to when I bought it.

Hisense make reasonably priced products with decent specs but their customer service is sorely lacking. I don't think either customer service rep even bothered to read my enquiry.
