Horrible backoffice support

Bonitas is a great medical aid, but their support services sucks.

I've been talking to them for almost a month regarding a payment that I made to them. They claim that they haven't received the payment while I confirmed with my bank that the payment definitely went through (we're banking at the same bank).

Now they've debited 2 months' worth of premiums and still can't find my original payment. Speaking to the call centre didn't help at all since they just refer it to the accounting department and the accounting department just keeps on saying that the money wasn't received.

I just wish that someone would actually go through the effort of really looking for my payment.
