Seriously disappointed with very shoddy service from Discovery

I have been on Discovery Health for 13 years and I'm on the second highest plan. I am the HR manager for my company so am well versed in administration of the scheme and how it all works. I resigned from my company and withdrew my membership from the group scheme via the online portal. I first emailed my change of banking details form with supporting documentation to administration on 28 May. That was 11 days ago! I didn’t get a reference and no one communicated that the hold up was because of needing to sign the document physically, rather than digitally, which I hadn’t done as I was relocating cities at the time and didn't have access to a printer or scanner. I called the call centre on the 30th as I hadn’t had confirmation of change of details. The woman I spoke to promised to come back to me, but didn’t, this after I emailed her all the documentation. On 31 May my company's Discovery Corporate Health Manager escalated to admin again. Again I heard nothing back. I heard nothing until 7 June, when the Corporate Health Manager notified me, after I emailed him on the 6th, that I needed to physically sign the document. I went to an internet café that day, printed, scanned and emailed the physically signed document to him. Which he re-sent to admin yesterday (8th). Another day has gone by with no reactivation of membership and now I’m going into the weekend with a suspended membership. Not a good idea when you have brittle bones and something could happen at any time! If I'm in an accident this weekend and am unconscious I could very likely end up in a government hospital. Not what you expect when you spend R4800 a month on medical aid! I called the call centre this evening to find out the status and they tell me if it’s gone to Admin it will take 3 – 5 business days! Which will take me to next Thursday without an active membership! Seems to me that Administration is where changes go to die. At this rate, I probably would have had coverage quicker if I’d changed schemes on 28th May! Honestly after 13 years I expect better service than this!
