Pathetic Customer Service

I have been trying to amend my Discovery Life policy since the 22nd of January this year to include a full Vitality, hence I was put on Vitality Lite/Active without my knowledge. I wanted to do this quicker so I could take advantage of the Virgin Active special which ends today. The guys have been sending me from Pillar to Post every time I phone this number ***. Just this week i phoned these guys every day, and they keep saying, we will give you feedback by COB, and then they never do. I am tired of them telling me stories because today they told me that their systems are not working.
