Unable to schedule an appointment online

I have completed the correct online form on the VFS website, so that I can apply for<br> a permanent residence Visa permit for a relative of mine.<br> <br> However, I cannot schedule for an appointment on the 24 of June 2015 online, because that date cannot be selected - at it's not just the 24th June . Right till December, there aren't available dates one can select as a<br> date of appointment <br> <br> I'm not sure whether this is a technical issue or what. <br> It's would be nice though, for VFS to supply us with info to WHY there no available dates for selection. <br> <br> Whatever the case might be, it's really frustrating not being able to book an appointment especially<br> because my relative (grandma) visa is going to expire soon.<br> <br> I need help now.<br> <br>
