Unauthorized vitality ****

I have contacted discovery and requested a recording of a call of an unauthorized Vitality billing, Instead I received a call from one of your consultants and she agreed with me of the unauthorized deduction from my account thru my employer. She was to come back to me regards to how the refund will be processed, to my surprise now I find an email saying I've not been billed. I have deductions on my salary advice deduction of vitality. Can u prove me with the proof of the non deduction and I can take it from there. I'm not happy with the services I'm getting from Discovery, as I'm not getting any solutions but even greater problems.
