Discovery must still discover good service

I logged a web call to cancel my Vitality after consulting the useless service bot. They rep**** on the web query via email and said i will be contacted within 10 days. This did not happen. They said via the Whatsapp service that they tried to contact me on 8 June. This is not true. I also checked my phone log. Their phone number is a waste of time. Keep on telling me that that I entered my info incorrectly, but it is correct.
