A Solution of the Puzzle

When I folded up some clothes I noticed that a pair of pants had been washed with a small piece of paper in one of its pockets.
On it were some important phone numbers, but, by then many of them had become unclear.
I wrote all combinations of numbers which seemed to be possible while guessing the remaining numbers on another piece of paper, and then I tried them to call them.

I have not made a mistake like this since I began to use smart phones.
I was in dismay. :-(

Oh no! I hope you are able to figure out the numbers.
