Most probably a number you did call (say, C) is call forwarding to that
other number.

If this is done by the telephone provider, instead of by initiating an
outgoing call and connecting the data paths, your number will still
appear as the originating one.

You should compare your clocks, then compare your call log files.

Less likely: 

Somebody with a Provider License is calling them faking to be you, either
due to malice, or due to a typo.

Those people are normally:
- telephone service providers
- 0800 number owners who want the 0800 number to appear on your display

etc.

Another possibility:

some country prefix isn't transferred correctly, and it isn't you, but
$someothercountryprefix+yournumber that is calling them.
