I Do Not Get Paid Until 28th of the Month, Can I Pay Then?

Yes, provided that you pay in advance of your instalment date not in arrears e.g. if your instalment date is 1 April you should pay that instalment on 28 March but not on 28 April. This way, you still only pay the same monthly amount (but a few days in advance) and you will then have January and February when you do not have to pay an instalment.
