Kash… what’s done is done - moving on… if you’ve completed the coursework for the MCS, would the institution provide you with that degree if you were to complete the undergrad degree? if that’s possible, then I’d say just complete your BCom or BA privately and get that MCS under your belt… even if you’re required to take a few more courses for the MCS to be able to graduate, it’s much more worth your while to get that designation rather than spending too much time on the undergraduate degree.
As others have noted here, an undergraduate degree is not sufficient for a job, but I understand that many jobs require a degree for eligibility purposes.
