I know, but its the best exchange in terms of support for a variety of coins, and speed. I reccomend submitting a support ticket, wait for a reply (I know it takes forever) and for cryptsy to disable the pin. Once (or if) you enable the pin code again, use a texting app to receive the pin (like text now, text free, voxox, or google voice)
Hope I could help
