Error while processing the request! Problem in sending email while doing IO operation

I have been having this issue for over a week? I phoned support and they said it will be fixed in 2 hours - (that was 5 days ago) - phoned them yesterday again and same answer - today the phone is ringing out (even though Im no1 in the que - eventually after 15 mins it stops!?

Can you tell me:

a) What the issue is?

b) When will it be fixed?

c) What is wrong with support?
