Prematurely worn out backcover by premature plastic aging

The backcover of my FP2 started to brittle at each of its angles, 7 months after the phone was shipped to me.
I have been using phone mainly inside and when I was carrying it outside it was either in my pocket or on a holder inside my car. It didn’t spend hours under the sun, mainly because I live in (rainy) Switzerland!
This being a manufacture issue, it should be sorted out under guaranty coverage! I have written to Fairphone 2 days ago and no answer! Still hoping!
