Irresponsible people

They keep losing my documents. It's getting so irritating. I submitted my information when I first started school in august last year. But in november, the new girl who took over the admin told me they hadn't received it. Fine, maybe the handover was messed up so I did her a favor, filling in the form again for her. Now, she emails me telling me I have yet to submit that form. EXCUSE ME, this is the THIRD time you're asking me for the form. And i am 100% sure that I filled it in and submitted it the past 2 times, coz my supervisor's signature is required! Now i have to get him to sign the very same form, for the 3rd time. When have i ever liked NUS admin? Never.
