Whats goin on with my tax refund?

I live in michigan and ive had this guy who lives in florida do my and my girlfriends taxes for the last 2 yrs,well this yr he did our taxes again,we have him do direct deposit both our refunds into my account(which was supposed to be on 1-18-11 when it was to be deposited and we receive it),my girlfriends was deposited but not mine,so i called and talked to him and he told me that he made a mistake on the routing number on my tax info and that's why i didn't get mine he said that when the irs sends it and the bank rejects it that they will mail me out a check and it should take no longer than 2 weeks to get it,well today(2-4-11)i decided to check the irs website wheres my refund and it says that my refund was deposited on 1-28-11,my question is if the routing number on my refund was wrong wouldn't the irs website say it was rejected or it is still processing,I have a feeling that maybe he stole my refund and had it sent to another account,I want to call the irs number that they give on the website but I dint have all the info,I have my refund ammount and my ss ,and what i claimed but i dont have all that he put down,should i be worried that he might have stole it or should i wait and see,how else can i find out what account it was put in or what has happend to it
