Did a just get scammed for my social security #?

I just gave my info over the phone with a Representative for a loan place and I applied the info he wanted on the screen and told me what to do step by step and as soon as I got to the next page he said ok I am going to place you on hold and transfer you and HUNG UP and I am now scared he has my bank info and SSN and I called back and it was the actual business but never got to anybody and I called again and now there is no answer or business or anything What should I do
