Your journey is practically identical to mine
@William **************
. Different branch of BB however.
I went through the same process on 28th August, and was told within a week it would be Un-frozen after BB head office had seen all the photocopied proof and read my form.
20 days later and still frozen. I went back to my branch this morning and saw the same employee as before. I was basically told to wait another week (maybe two) because their head office worked slowly and there were a lot to process!
