Sim card locked

<p>Hi i bought a sim card so that i can use it for data and email about 7 months ago. i then had to go out the country for work which ended up being longer than expected. My number was then blocked which is reasonable and i knew would happen after 6 month. </p> <p>But the problem is getting the number to work again, ive been sent pillar to post and have had no success in the last week from every vodacom shop i visit. They insist the sim is ****** locked and i need to give them 5 numbers dialled from this sim even after i explain this was meant to be a data sim. i even took the original sim card with the puk number in the original packaging and they say theres nothing they can do. what makes matters worse is that my vodamail email is linked to this sim and i have no access to my mails which is becoming a nightmare.</p>
