Good day… Sorry to hear of your troubles, but it seems that your issues fall under the parameters of the 1 year warranty.
My F5, about same age of yours, the keys started coming off. I hounded GearBest for about a week, escalating the issue as far as I could. I requested the exact verbage of their 1 year warranty that deemed my issue as NOT COVERED. They could not. I had to send mine to an office in California and paid $20 to have a replacement expidited and received it here in Phoenix in 2 days.
I was firm, but cordial.
It took effort on my part. With the time difference, language barrier and always speaking with different representatives. Request 1 designated supervisor personally handle your case.
From what I remember of the warranty I don’t recall an issue like your not being covered. I can’t see any company that would deny your claim unless there is external neglegent handling on your part.
If you have the time, huge bottle of asprin, I would fight.
Good luck, sorry for the rambling!
