Thanks for sharing your profile. Unfortunately, a gap from employment does affect your candidacy. Top schools are not just looking for strong professional leadership and performance, though; they are also looking for strong academic performance and strong extracurricular and community leadership. I would suggest that given the type of role you held at HSBC (customer service) and the gap in employment, combined with the fact that you already have an MBA and that you don't have strong extracurricular and leadership experience, an MBA from a top university may be out of reach. Urbana might be possible, but it will also depends on your GMAT score in terms of which programs you'd be able to gain admissions for.
Best of luck,
