Vodacom Useless

Before traveling abroad, I activated international roaming with Vodacom. On arrival in Ghana I had no communications. I was there overnight before traveling to Liberia. On arrival in Liberia there was also no available carrier. I checked on Vodacoms website and the have an agreement with Commcell in Liberia. I asked my wife to contact them to find out why I cannot access the network. They informed my wife that they cannot assist here, only I can query this. How do I query this when I am in Liberia, with no communication available to me and no E-mail address for Vodacom?
