International roaming NOT activated

I cannot believe the incompetence I have had to deal with when it comes to MTN<br> <br> I called into the call centre twice to confirm that international roaming has been activated on my number and now I am out of the country and it has not been activated. <br> <br> The Call Centre confirmed on the 15 September that it had definitely been activated but as of today my phone still says no service.<br> <br> I need this urgently fixed and yet I must now try and keep calling them from a different network and waste my money to try have them activate this.<br> <br> MTN is currently the most expensive provider so you expect good service but yet again they have no idea what service is.<br> <br> Samantha King
