Medibank - Frankston

Paying customer for over 10 years. Had an issue making a claim. When I went to the store for help with a declined hicaps receipt, was met with the most dismissive and rude customer service I have ever experienced. Was essentially looked up and down and instructed to go and pay my bills! Was not offered any assistance to resolve the issue. Which as it turns out, was caused by a staff member cancelling my direct debits when I updated my payment details. Disgraceful. Why have I wasted tens of thousands of dollars when I get this type of response?
