Can't Reach Barbados

Why is it that I can't seem to use the calling cards at the local 7-11 to reach Barbados? I tried so many times, I had to give up and call customer service. At first, they couldn't locate Barbados. Then, they said I need to add 1 before the country code to reach it... but I know that isn't true as the time I tried to dial 1 before 246 (from here), I reached a country I never heard of before! (Do you know where Diego Garcia is?)

I now have the company fax machine sending a fax. And in future I will use the handy tools my friend in California sent me. You can find out exactly what to dial from one place to anotherat Country Calling Codes.

And after you know how to dial, you can click here to buy calling cards online. I think they are not so cheap FROM other places aside from the US, but perhaps they can at least allow you to reach certain countries which local companies are not even aware exist.
