Terrible service and dishonest agents caused my medical cover to be frozen

Horrible service from Discovery after being a loyal medical aid and banking customer for years. Asked them to switch my debit order date to the 1st for this month, which they did not do resulting in the debit order failing. For a whole week I've been requesting they do the debit order again, 4 times I have been told it will definitely go off at the end of that day and I am still waiting. Because of their incompetence my cover has been frozen. After requesting that they escalate, I was again promised a callback which did not happen. How is it possible that 3 different consultants are not well trained enough to resolve a simple query. I am considering dropping all my Discovery products.
