Oh dear, I had a similar experience when I applied for DS1 a few years ago. How was it left, are they going to look into it and call you back? In the end I got to speak to a very helpful person (having endured many not so much) and long story short it was in the bank before I'd been notified he'd been awarded it.
Disinterested lady said she'd arrange call back, I hope she noted my number properly. She started the call too quiet and by the end was an incomprehensible whisper- I swear she moved the mouthpiece further and further away because the line was fine!!
