Complaints and Queries

For the last 2yrs I am constantly having issues with staff and same complaint queries that just do not get resolved and I made liable with constant costs to me and long time waisting with no resolution. Almost 2yrs trying for vodacom to assist and resolve queries an complaints. Dont get to top Management to handle the query... its as this company only has entry employees running the company and do as they please. Owners and desission makers dont exist at all. So fedup as I have been a loyal client since vodacom started out in SA. How am I ever going to get joy out of this company. Yet when pmt is required they are first in line yet when queries com up and need to be resolved everyone is dead and nobody can or knows how to assist. Need someone in charge to phone me asap and sort me out once and for all for all my losses and cost I have accured from Vodacom not doing there work they get paid to for!!!!
