Worst Customer Service

The worst customer experience. I spoke to a consultant in Feb and advised that I'm adding a dependent and want my first debit order to go off on the 28th of Feb to my surprise an incorrect amount went off and my cover was cancelled I've been trying to call through the contact center however it experience is heinous ,I keep getting disconnected and one agent even hung up on me while I was on hold for more than 10 min

I had to re apply online but I cannot add the emergency cover , I requested to be contacted back and I'm still waiting .
