Termination of Medcal Scheme contract

After due consideration and receiving a 28% increase in my monthly Medical scheme contribution. I made the decision on the 4th of January 2019, to terminate my contract. Sending two emails, and two contact requests on the website, I've been blatantly ignored by the company. These were also followed up with two phone calls. Phone call one (08 Jan '19) , my wife was told that no correspondence were received - a blatant lie by the cosultant. Phone call two (09 Jan '19), I was told by the consult that an immediate follow-up will be done and an email will be sent. Needless to say, NO response were received.

I am in urgent need of a Cancellation Certificate.

80 hours "non" respond time for a company with a slogan reading - "Simply complete the form below and we’ll get back to you quicker than you can say quality healthcare cover." - just don't sound professional.

Hope to have a speedy response after publishing this.
