International Roaming Query (Bad Service)

The previous week I've requested international call and data roaming from MTN-SA. I'm now in South Korea and I can't make calls, I'm stuck in a foreign country without a phone. I need to make calls, this is very urgent. Mtn-SA assured me that my sim card/cell number is activated for international roaming when I phoned-in before I left for overseas on the 7th April 2016. Their consultant allegedly told me everything was in order. This is such an absurd poor service. This make sick. I have send them Mtn-SA a couple of e-mails. This is their lame excuse:<br> <br> \Thank you for emailing Customer Care.<br> <br> We apologize for the delayed response.<br> <br> Kindly be advised that you need to be in the country for us to activate your International Roaming.<br> <br> We trust that you find the above in order.\"<br> <br> I don't need an excuse, I need a working international roaming service.<br> <br> <br> "
