I'd be minded to call TEC and confirm the new form has been received and everything is in order. Your second email was still "in-time", but you cannot afford any more mishaps.
Such a nightmare getting in touch with these people!
Just been on hold for a total of 2 hours.
In the morning I was on hold for 35 min until someone answered, then I couldn't hear anything, silence. They ended up hanging up after 10 seconds.
In the afternoon I stayed on hold for over 1:30 hrs until my turn came, then the exact same thing. Silence. Nobody speaking, not even a sound.
The second time around I was talking and let them know that I cannot hear.
I read out my PCN number to them and slowly explained the situation.
I believe someone might have been listening as they didn't hang up, even though I couldn't hear them, for a good 2-3 minutes, until I hung up.
I'll try again tomorrow...
