Acceptable broker practice ?

After being offered rates through a broker I naturally wanted to know more and asked questions along the lines of for example : 'Do any of the products on offer have administrative charges for overpayments or other direct debit / extra payment variations?' . This was because I was supplied scant information.

The broker replied with 'If you want to proceed let me know and I will email you the answers to your earliest questions' Is this normal behaviour? I would expect to be in receipt of all available information regarding offers before proceeding.

In one word NO.
I would not find it acceptable at all and would look for a new broker straight away.
