Siweida Fishing Rod

I bought this fishing rod and in less than 2 mounts it broke. I was told its my fault because I overload it, but I never used more than 90 gram weight . The casting weight of the rod is 40-120 grams . In my opinion you can not cast more than 60 gram with this rod. Now I regret that I did not pay about 50% more and bye fishing rod from proven make.
