CANNOT MAKE APPOINTMENT AFTER PAYMENT MADE

I have filled in online forms for my PR application during Feb and paid for it. Then i made an appointment, however, i could not obtain the police clearance before the appointment date, so i went back to VFS website to reschedule, it allowed my to reschedule, but i could not choose any date during March, so i contacted the customer service, they have told me that the schedule for March has not been released yet. Due to my original appointment date is very close by then, so i decided to cancel the original appoint first and make a new appointment whenever the schedule for March is released by VFS. I have then tried to make a new appointment for an month without success, the website just turns into a yellow error page after i click on \make appointment\". I tired on different browsers and computers. Then i sent an email to query about this, customer service just rep**** they have forwarded the email to another department, until now, i have not received any response on how should i make an appointment if the website is broken.<br> I'd think that if the whole process must be made via website, at least VFS should make sure the website works."
