To obtain an answer to your Question, I phone the office of Sayyid Sistani and they said that:
For a talaq to be correct has to have the following conditions:
1- You have to have two believing adults as your witness
2- The woman has to be clean of her menstrual period and also shouldn't be pregnant
3- Proper Arabic words need to be uttered for the act to take place.
In your case, since the 'Sighah' of talaq was not recited, your marriage is still at place.
