No feedback & CALL CENTRE CANNOT HANDLE QUERIES

Called the call center 04/01/16 and spoke to a agent about 3 queries, agents said will refer to team leader and will get back to to me. No call received by 06/01/16 so I phoned the team leader says no notes were put on the system except abt 2016 benefit guide. I told her to listen to call an told her the queries still no call recd from team leader. Phoned on Thursday afternoon team leader not in so I asked for Shiren who told the agent will call me as yet she has not contacted me. I phoned today to the switchboard a number of times toi Danielle to find out who is the superior to Shireen and was just trf to Pretoria who cut me off. Danielle cut me off few times. The switchboard operator need to handle calls more professionally and not cut calls of and to give their name. Willa appreciate someone in an executive position to phone me.
