Horrifying Customer Service

I have been a member with Discovery Medical Aid since 2012, I have been in the process of changing employers but not one consultant cared to call me or make contact in order to explain the process however I get a bill for debt??? The installment for March is only due on 1 April but this is the sort of communication you with no consideration for your clients?! Without your advice how on Earth am I am supposed to have known the costs incurred if any? Knowing that my monthly are up to date? Despicable how you allow your clients incur debt with not even the courtesy of call.

why can't clients expect the same customer service as when we are spending money and when we need Discovery to actually contact us as a service provider?
