Terrible service and agents

I've been a customer of vox for the past 6 years. Yesterday my line was cancelled without any communication or to my knowledge. I've spent hours on calls getting thrown around to different departments and even hung up on. No one is able to give me an explanation or a resolution which is very concerning. I am currently paying for a service that has been cancelling and am already down R200 in airtime trying to get through to the agents and get a resolution
