Samsung Galaxy Y Assistance Needed

[WHU010]

I am sure this is going to sound very strange but I am having a problem when I dial a new mobile number and then try to save it in my contacts -it comes up with a Ukranian alphabet name and when you check the other details it shows a ukranian email address too!! See I said this was very strange.....I eventually manage to delete this name and address and type in whose name I require but I am completely at a loss as to why this should happen. Has anyone else had a similar problem? I really dont want to have to go back to the vodafone shop at the moment as its in a large shopping centre and will be manic.
