To address your first query, see if you cancel the admission say on 16th Aug and classes have already commenced on 05th Aug but the seat is allotted to someone else before 20th Aug, then your entire 1 month fees will be cut before giving you the refund amount. If the seat is not filled then you will get no refund. However, I am unsure whether they will allow students to join the college after 20th Aug.
As far as your second query goes, I am no expert and am joining the college this year like you, so I cannot tell you which one is better as I don't have a strong reason to back my statement. BUTTTT as far as the rankings go, based on faculty, placement, infra, etc. Met=Xaviers>Chetana>IES>LALA.
Good luck with your decision making process. Hope it clears a bit of your confusion.
