Unprofessional disappointing service

No feedback to queries or calls - How does one correspond with Mancosa guys ? Tried to call the agent, each time he never calls back nor respond to my emails. This is tiring guys … why are we allocated to an agent if they don’t even bother responding ? This is how I spend my everyday week - holding on for Lee-Roy Ntokwenzani, the whole day. So he never reads my emails until I get hold of him after 30 tries per day ? Like really … this is unprofessional
