WTF!!!!! Is Going On This Is REALLY PISSING ME OFF!!!!

I can't log in to edit my clients site and they have paid me in full to get this completed today! What kind of service is this seriously? How long do I have to wait now before I can edit my clients site? And what are we as customers receiving for this HUGE INCONVIENCE????? You guys have our paying clients getting pissed at us for this service and it's not even our fault! So what do I do now?
