Are you in your own skype account? I only ask as you said it came back with wrong person.
I often get a skype download new version or however they put it, I download and would be asked to buy skype credit, I usually ignore all that bit and just go on to my profile and carry on skyping, I don't know how to help you now with your problem tamaris. I'm a silver surfer and would have to wait for one of the boys to come in to help me out of a predicament like yours. I could only get as far as I had tried to help you with. I am sorry, hope someone with a more technical mind can assist you
