<p>I have been trying to get anyone and Vodacom to help for two weeks. Emails are not being answered. I am in Korea and unable to use a Korean network sim because Vodacom has locked my sim onto their network! Nobody is willing to respond to me to get it unlocked from the Vodacom network. This us crazy! I am in a foreign country and I cannot contact my family unless I find a random wifi area. I cannot call home! </p> <p>I have a phone Contract with fnb that is only my phone payments My vodacom sim card is on prepaid... Vodacom should have never locked my sim!</p> <p>For the love of god Vodacom help me! Unlock your hold on my phone so I can call my family! </p>
