The sales rep has used a(n) Sharp angle close .
Explanation:
The Sharp Angle Closing Method is better used if the prospect will possibly buy the offer, although there is a rude opposition to it. They pose this opposition as a challenge like "can you deliver" or "there's a question" or so on.
They can answer this question with a sharp angle strategy in the hope to close the deal with yet another relevant question.
The deal is done and dusted if you get a positive reaction. If not, you know they are either not critical or there is another question if you get a negative reply. Here you have a second opportunity to clarify any other problems.
