Discovery MILES away from good service

Although indicating Discovery health it seems the whole Discovery is becoming problematic. It started with attempting to place a new item on my insurance plan. Very clear email requesting the changes and attached proof of buying the item. I received a replay addressing me by a name I don't know and requesting information that is on the original email. After I send a replay email I received a replay email indicating that changes has been made and Discovery will send my new updated policy. NO I had to request it as they did not send it. I then asked to be contacted by a supervisor to explain the lack of customer service and I am still waiting, this was on 22 July 2020(WRefNo#***#- -MailRef#***#). Next problem is with Discovery health how have the total incorrect information on my Vitality profile and it seems they refuse to accept my medical evidence send to them regarding my full medical completed in July 2020. Discovery did acknowledge receipt of the documentation, but it seems don't want to give me my Vitality points as per their Vitality points system. Discovery also indicates that I have done tests within the year, which I have not done and it seems to me that after their system change from point to miles have confused their systems to indicate tests done that was not done and other they just do not give the points. Trying to raise a query with then does not work as their website and app, although having a link which indicates "Send Query" it only loops to a page that have FAQ and now were to send a complain or query, except to loop back to send a query and the same page. There is know way online to contact them and I feel it is unfair to expect the customer to pay for phone calls to correct their mistakes and you don't get any assistance from their call center other than a message indicating they will call you ( ***)? AS indicating in their current marketing slogan, they have changes for the worse!!
