vodacom three department's clueless

I signed up for Unisa student 3G contract with vodacom on 05 February 2015, the data was loaded next day now I went to enquiry with call centre to know as from now which day of the month will data allocated. I was transferred from main call centre to contract department which stated they don't know anything about Unisa 3G contract then I was transferred to Sale s department Same thing happened they transferred me to data department which clearly stated they don't know anything about Unisa Student 3G contract. What surprise's me is that how come all department's of Vodacom don't know about Unisa 3G contract but unisa stated all enquiries should be forwarded to Vodacom beside billing enquiries which they will handle. Who is fooling who here? I will appreciate some decent explanation not the c***p your consultant's feed us.
