Beautiful dress straps r poorly made..just by fitting it on and straps broke

Bought this dress for my best friends Wedding and absolutely loved it when it arrived. Tried it on and it fit perfectly, the color was vibrant and dress was beautiful....however, the rhinestone straps had protective paper coverings that I did NOT open until I was about to put it on day of Wedding and unfortunately one of the rhinestone straps was BROKEN!!! To say I was heartbroken, disappointed and incredibly upset is an understatement. Shame on me for not checking straps prior but still this is not acceptable especially since their is no phone number and I have sent several request regarding issue on Monday Oct 3rd 4 days ago :( My advice is when you try on dress look at EVERYTHING and read reviews because it clearly shows several reviews saying straps broke!! This wardrobe malfunction caused me to miss my friends Wedding vows as I was late due to this and for that I am extremely sad. PLEASE contact me I would like to exchange dress for same one but it has low stock and no one is getting back to me. Very sad :(
