Bad Customer Service

Bad service i have received from Discovery Healthy. I was changing plans and i was asked to pay money for that particular and i did. When i followed up i was told that i do not qualify for the plan and i was given the information by one of the Consultants only to find out she deceived me. I had to reply and move to another and was also required to add money on top what i have paid and a day later i was told that i have an outstanding amount of R 300 or else the plan will be put on hold. I escalated this matter a is expect that the consultant should to take some responsibility. I have not received any communication from Discovery .
