A friend got a number of anonymous texts at the begining of the year saying his wife was having an affair. This turned out to be true but they decided to make a go of it. The texts have now started again, saying he is being taken for a fool. The recent texts are from a different number but he is pretty certain they are from the same person as they have an odd way of writing. He would really like to know who is sending them, he has tried phoning and texting the numbers but can get no reponse. Is there a way to trace who "owns" a number?
