Rockbag Starline bass guitar Bag

I bought this bag 3 months ago and the first thing I noticed was that the shoulder straps were not attached as shown in the misleading pictures, but they needed to be strapped on and secured using a carabiner. I was not pleased to discover this because it wasn't what I was showed on the site and it just looked and felt a bit weak. Today however I hadn't realised the strap had come off causing all the weight to rest on the carabiner and after a whole day it snapped. Now I understand that failing to realise the strap had come off is my fault but the only reason i bought this case was for the shoulder straps and now one of them is broken so the bag is useless to me. So please upload a photo that shows how they really work cause personally I wouldn't have bought this bag had I known. This is an expensive bag and I expect everything to be perfect. Its sad to see a good company like Rockbag realising they have the monopoly and thinking they can drop the quality like this and mislead customers. Very disappointed
