Inured Spouse Claim

So after a few months of bugging the IRS they finally accepted and approved my injured spouse form. I got a letter in the mail on June 18 stating that my adjustment was approved and it states that "We will send you a refund, including any interest due, in a few weeks as long as you owe no other tax or non-tax government  debts." I was trying to inquire if anyone else has received a letter like this and if so did it really take the 3 full weeks or is there a possibility of me receiving the refund sooner?
