Extremely bad service

Worst experience ever in my life. I have been waiting for a membership card since February 2018 and I have not received it as yet. They have my correct postal address however I never receive the card. I than requested in October for it to be delivered at my work office but still nothing. I offered to go and collect at their office and they refused. I am stuck without a membership card since February 2018 to date. I don't even know how a discovery membership card looks. When I needed to add my parents as dependents it was a hassle that also took more that 6 months. When there were eventually added there are given waiting period of 12 months for sickness they tested negative for. Which makes no sense at all. I am extremely disappointed and I don't look forward to dealing with Discovery going forward.
