waiting for exam results.. very urgent!!!!

[tonny]

i am a msc student submitting my dissertation in 21 december 2009. i was meant to finish my studies on august 2009 and hence got a visa till 28 december 2009. ( 4 months extra)

During my studies i applied for an extension for my dissertation submission date from august 2009 to december 2009 from university.

i forgot to update this information to home office. My student visa expires on 28 december 2009 just after submitting my dissertation on 21 december 2009 and hence have no time to wait for my results .

is it possible to get a visa for waiting for results which are due in april? or do i have to travel home to wait for my results?.. the home office know i finished my studies in september 2009 but i am still in University till december. The university has refused to give me a visa letter to wait for results or even dissertation extension letter to prove this. They claim i have enough time to submit my disertation and can't do a letter to wait for results.

Please advise on what to do...as time is running quite fast...
