Completely disgusted by the customer service within Vitality

I am so disappointed with the manner in which my query is being handled by discovery vitality regarding an agents error .I had called in this year February to join vitality and the agent that had assisted me ,informed me that I qualified for a 3 month free trial.I then decided to take up the offer anticipating that my premium of R399 would run in May yet to my surprise ,R1196 was debited from my account .I followed this up with vitality and they referred me to other department (Billing ,cancellation and discovery health ).All these departments keep either escalating or referring me to another department.I did speak to a spec agent who sent both an email and sms on the 16th of June ,informing me that a refund would be made into my account in 3 days after they had listened to the recording .I am still waiting for the refund and I still have no department that is active in the matter . Im very disappointed by this whole situation as I’ve spent so much money calling for feedback and spending so much time and data trying to reach the relevant department which til this day no one wants to account for the matter .
