Atrocious service but quick to increase rates - even on first month of joining

I only joined Discovery Health Coastal Saver on 1 June 2021. Today, 31 July 2021, I receive a notification that my premium will increase. This is unacceptable. When I received the quote, I was not advised of an increase one month in. Their service is atrocious. I repeatedly send them FB Messenger notices enquiring about incorrect points allocated, not changing my surname on the Kulula Discovery Vitality platform after I got married as they have done across my other Discovery platforms - I've waited two months and still I cannot book a flight on Kulula due to my name being incorrect on their system. Very quick to increase your rates and debit your account, but absolutely atrocious at customer service. If they were half as quick at dealing with customer queries as they were with their price increases, they would be a fabulous organisation. But, sadly, and immensely frustrating for the customer, their service is extremely poor and unsatisfactory.
