Samsung Rugby A837

Yesterday I dropped my phone about 2’ on concrete. It split in half, but NOT a scratch. This phone has been advertised as a durable phone. I even asked the salesperson about concrete because I work on it. She said it can withstand a normal fall of 3' onto concrete. Forgot, before I go on…I didn’t get the insurance, and I’ve had it more than 30 days but less than 90 days. Anyway, after (3) calls to Samsung explaining how this had to have a defect in the hinge…$70 and we can fix you right up. Has anyone else had this problem? Any advice on getting it repaired without cost or reduced costed?
