No, sorry. All domain sales are final. If you want a differently-spelled domain than the one you bought, you must purchase that also.
Hint: All is not lost -- you can still benefit from owning your misspelled
domain. If you have a hosting account that allows Add-On Domains and/or Domain
Parking (such as any of the paid-level hosting accounts offered at Mumbai
Hosting), you can redirect the mis-spelled domain to your real domain. After
all, if you misspelled it, chances are someone else may try to find your site
that way too. Why not help them out? ;) In fact it is quite common practice
among successful sites to purchase dozens of domains with different spellings
for just this reason.
