I don't have the phone number, google it and you should be well off. Don't rely on the phone. Go to their office and ask to see the card personally. If it looks undamaged, then fine, ask for a replacement. Talk to some senior officials and not to the ones on the desk. They must have given you a receipt of some kind, stating they they have the card with them. Use that receipt against them. If the card looks damaged, then blame them in the court for it as it seems you did not damage it yourself.
