disgusting service

I submitted a claim to Discovery on the 23 September 2021, today is the 26 October and I still have not received my money from Discovery. The reason they gave me is because the doctors invoice did not have an ICD number, which is not my fault. I gave them the doctors number so they could sort it out directly with the doctor and to date, I have not received any correspondence or curtesy call notifying me of what is happening. Discovery charges ridiculous premiums and they are so quick to take a persons money, but when it comes to refunding money, they don't bother contacting the person and they take FOREVER to sort out a problem!! Very disappointing indeed. Not impressed with them at all.
