Frustration

Trying to find one person to help consistently is impossible. Each call takes 20 minutes on hold to get to speak to an individual and each time I start afresh as can never speak to same person and no one can see my emails or problem discussed previously at call centre. The blame gets shifted to other departments or vumatel and then back again. Email replies are never individualised and replies are directed to general support and I start all over again..if I'm lucky to get a response on same day.
