received a call from this number 2 Mar 11. Trying to call but always busy. Will keep trying.

I too had 3 calls in all from this number and a similar one with the last two digits different.  I've tried calling back with an engaged like sound the only reply.   Bloody annoying!

Ah that makes sense to me now, I have had numerous missed calls from this number and it says user busy when I try to call it back. I purchased a lottery ticket through them last year now I'm paying for it, constantly getting phone calls for other lotteries, will definitely get them to take me off the list. Thanks for everyone helping me figure out who this was!

Who Is this - they keep calling my mobile from a similar number 3 -4 times a day. Leaves no message.

I receive calls from this number everyday during working hours.  Even up to 5 times a day.

i got call from this number,,, i replied him but can't answer at all .. it says number is busy..

Just got a call from this number today (missed call) and wondered who it was.  Like others, when I called this number it was engaged.  Thanks to the above contributors, the puzzle is solved.  I too have bought a lottery ticket from the Muscular Distrophy people.
