Specialised Feeds declined despite comms and previous Hellopeter post

My Dad, a stage four oral cancer patient, who's mouth is riddled with cancer, and has a feeding peg on his stomach, as a means of getting nutrition and required meals in, had been granted 24 units of Ensure per month, that will be covered out of the Out Of Hospital Specialised Feeds. 12 units of Ensure Vigour was purchased and my dad submitted his claim through on the 11th of May 2021. To date, despite numerous emails, and follow ups, the claim has still not be honoured and paid to my dad. How does a prescribed feed, which has been authorised by yourselves, gets declined despite every single requirement has been fulfilled. This is not the way you treat a 69 year old, stage 4 cancer patient, who is reliant on these feeds every 2 hours. I am utterly disgusted at the manner my dad's entire treatment has been handled by Discovery.
