Never came back to me after I have lodged a query

I phoned Discovery Vitality last year in November/December.<br> <br> I had a query with regards to my Healthy Gear Cash-backs, as I believed there was amounts owed to me outstanding.<br> <br> Firstly, when I asked them about my cash-backs, they rep**** and said they have nothing whatsoever on their system and that they would look into the problem. The lady then told me she would call me back within a week. This was the 11th or the 12th of December 2014.<br> <br> One of their managers then only called me back on January the 6th 2015.<br> <br> He explained that i have exceeded my limit of cash-backs (Which I could not believe as I had to make purchases of R15000).<br> <br> I asked him to send me a report stating what i have purchased, when and how many cash I got back.<br> <br> It is almost a month later and I still haven't received any feedback.<br> <br> This is really poor service.
