Roaming not activated

I called 808 to ensure that my roaming was activated before coming to Europe. Now stuck in Spain without roaming as the request was not carried out by MTN even though I was assured it would be. I am losing money as a result and would appreciate it if someone at MTN can fix the situation immediately and let me know via email that it was corrected. Like others mentioned on the net, the call centre numbers do not seem to work from overseas. I am also obviously not reachable via my mobile as MTN roaming is not working.
