I had your EXACT problem a few years ago. Company name started with a blocker sound, 'C', it was an acronym so pronounced 'See'. S is a block for me. Several excruciating phone calls 'hello I'm calling from s..s..s..s.s.see...see.ssseeeeee' in an open plan office + the sideways glances. Was hell. Anyway, I got around it with a substitute, 'E', and just mumbled slightly. Worked a charm. What cheats have you tried OP?
