Still waiting for membership cards

On 19 November 2015 I gave Fedhealth written notice that I will change the medical aid plan as from 2016. I enquired 3 times via the website/email for the new cards and every time I got the same answer - in 2 to 3 weeks time. It also seems as our membership number changed. I receive correspondence on 2 membership numbers. From the first notice it is almost 4 months that I struggle to get new cards. This is not acceptable. I have proof of all the emails and will be happy to make it available.<br>
