Call received through on our administration department line claiming to be from Dell Technologies and asked to speak to whoever was in charge of our IT Department. Asked to send an email through to our info inbox and he replied with "my emails are internal only" pretty sure that's not a thing but sure. Had a good laugh with our IT guy about that part.

Called my business' customer service line saying they're from Dell asking to be put through to IT. We are running Dell servers, but Dell wouldn't phone our customer services line to get in touch with us; they'd email our IT team directly.
