When I called the number a machine informed me that it was "Gemma Communications, a leader in the Canadian communications outsourcing industry."  But yes, you can press 1 for English, and then when the computer reads your phone number back to you, press 1 to say that you want your number removed within 24 hours.  
And then hope it works.

k figure this one out..i was getting calls from this number too..and now tonight again..and this time they say they are from petro points not citibank this time

yes they are calling me all the time too, makes me want to put back the call blocking feature again

I get this number calling on a regular basis and they never leave any message. Just more random annoying telemarketers!

Yeah just call the number back. Press 1 for english and then it will prompt you to remove your phone number.

good luck!

The company is a marketing company called Gemmeca Communications.  I'm not sure how they spell it.  I haven't stopped getting these calls even AFTER I have removed my number from their list.  I'm trying one more time and then I think I'm going to do some searching and find out from the Better Business Bureau what I can do.  I know that once you say "stop calling me at this number" and "I don't want to receive anymore correspondence from your company via mail or phone" They, bylaw, have to leave you alone!  So, hopefully this works.
