You should have been emailed your password when you saved your original quotation or when you ordered it. If not, there isn't to my knowledge but I'm no expert x)
There will not be a way to track orders without logging in as the details and information are unique to you.
In terms of passwords and/or tracking it however, your best bet is to contact PCS, either by email, phone or live chat and get either a password resent to your email and/or get an update on your order
Agreed, there should have been a few emails sent out when you made the order one of which should have contained a password. If not, I would recommend giving PCS a call to get access to your account or email/online chat (phone would be quickest though)
