Discovery Health call centre

Absolutely shocking service from the Discovery Health. I tried to get hold of them 8 times with no success regarding a covid 19 testing enquiry. Each time my call was cut off, sent to a non existing extension, sent to voice mail or transferred to an agent who couldn't hear me. The website also doesn't answer my questions. The only useful person was ****hka from Bankmed who at least took the time to call me back.
