Nintendo customer service... To serve or not to serve?

I am a long time Nintendofan and often called fanboy. I owned or own nearly all of their systems and basically only play Nintendo first party games. This i mentioned to prove that the following is no rant.

The analoge stick of the left Joy-Con had a crack i discovered. This probably happened after it fell once. I had not paid attention to it. Just a crack in the upper part where you lay your thumb on. But i saw it again recently and noted i could flip it, so it will break eventually. I decided to send it to Nintendo. The porto costs were euro 6,95.

Then a few days later they mail me and basically force me to choose between three very weird options. They even summed them up numbered.

1 We don't touch the product and return it for 11 euro

2 We repair and possibly revise the product for euro 36,30

3 You don't agree with the costs and we'll keep the product and destroy it. (end)

This is how they mailed me, referring to the Joy-Con only as product. Charging me euro 4,05 more than what i had to pay at the postal office.

Furthermore, why do they even consider revising my Joy-Cons without consulting me and for such a small defect?

I feel Nintendo is losing their contact with their fanbase.
