Over the last 30 years, the last 3 days of my life, have been the most appalling customer service from Sizwe / 3 Sixty Health, I have ever interacted with in my life. AND STILL, my problem (which was created by them, themselves) is still not sorted out. We requested that ONE dependent be cancelled, they never did that. Countless calls, emails and being cut off. I have spent the last 3 days emailing the said PROOF that they want, confirming the notice period which is April and not June and I am ignored. Totally. Yet, the PROOF of cancellation was sent to their membership department by their own staff member. Now they send confirmation of cancelling of the whole thing dating it as June being the notice period instead of April which means ANOTHER debit order will run on the 1st June. Please, DO NOT JOIN SIZWE / 3 SIXTY HEALTH EVER !
