You must be paid for all the time you worked up through when you quit or resigned; there are no legal grounds for not paying you your salary or wages. If they will not pay voluntarily, you could sue them for the money; depending on how much is owed, you may wish to sue in small claims court, where you can act as your own attorney, thereby saving on legal fees (also, small claims cases tend to move faster, leading to quicker resolutions).You may not however recover 2% interest per day--or any interest. Interest is only recoverable if there was some agreement in place (e.g. a contract) stating that in the event of late or nonpayment, you would be owed interest. Otherwise, you have no legal basis for  the claim--you may only recover the actual wages owed. (Besides--2% interest per day would be usury, or a criminally high level of interest, beyond that permitted by law, as well as being completely unwarranted, even if it were legal, at time when mortgages go for 4% per year.)
