Switching lenders? Student loan repayment....?

Hi, back in 06, I was mislead by Sallie Mae through the consolidation process (another story all together) and long story short, I have did not consolidated my stafford loans. It equals to about 22k. My question is, since I am extremely dissatified with Sallie Mae's service and dishonesty so far - can I switch to another company now and maybe consolidate at a later time?
